Figure 3 shows an intramuscular infraspinatous cyst. 2010;83(988):e79-82. T1: typically ganglia are low signal although high proteinaceous content or hemorrhage may result in lesions appearing isointense or hyperintense on T1 weighted images. Cookies policy. MRI MRI is probably the best test to show changes in the soft tissues of the sinus tarsi including inflammation, scar tissue formation or ligamentous injuries. The MRI protocol that better demonstrates facet joint SCs and GCs in the spine should include at least T2-weighted sequences acquired in both axial and sagittal planes [5, 6]. The sinus tarsi is an anatomic space between the inferior aspect of the talus and the superior aspect of the calcaneus, anterior to the posterior subtalar joint. An identifiable thin stalk communicating to the joint space is not infrequent. Kim S, Park J, Choi J, Rhee S, Shim S. Intratendinous Ganglion Cyst of the Semimembranosus Tendon. Terms and Conditions, 02:48. Clin Pract. Terminology Ganglion cysts are sometimes also simply referred to as ganglia or a ganglion, but should not be confused with the anatomical term ganglion. As its name suggests, paralabral cysts are usually found close to the labrum. The T1-hyperintense fat in the sinus tarsi space is replaced by either fluid or scar tissue, and the ligaments may be disrupted. MSK - Clinical Conditions - Ankle and Foot. An MRI scan may indicate excessive fluid in the sinus tarsi canal. Sinus tarsi syndrome is caused by hemorrhage or/and inflammation of the synovial recesses of the sinus tarsi with or without tears of the associated ligaments. Patient Data Age: 14 years Gender: Male MRI Coronal T2 Coronal STIR Sagittal T1 MRI Coronal T2 Treatment of ganglion cysts in the sinus tarsi typically consists of surgical excision. 6. 11. They occur more commonly in young women (especially in and around the hand) 7. Stability of the subtalar joint is assessed with medial and lateral subtalar joint glides performed by moving the calcaneus over a stabilized talus in the transverse plane and with subtalar joint distraction. Sinus Tarsi Ganglion Cyst Excision and Brostrm-Gould Procedure for Chronic Ankle Instability. Most GCs in the wrist are asymptomatic and easily diagnosed by physical examination, seen as a smooth nodular tumefaction of firm consistency on palpation of 12cm that transilluminates, imaging remaining reserved for less obvious cases, especially those presenting with sensory and/or motor symptoms due to nerve compression. Symptoms. Ganglion cysts are noncancerous lumps that most commonly develop along the tendons or joints of your wrists or hands. Regardless of the type of cyst depicted on MRI, considering the strong association, labral or rotator cuff tears must always be ruled out, as well as muscle atrophy. 2016;36(6):1688-700. Imaging acquisition of at least two perpendicular planes is mandatory, usually including the following weighted-sequences: T1, proton-density (PD) or T2, with and without fat suppression (FS), or short inversion time inversion-recovery (STIR) [3]. Insights Imaging 4:257272. The contents of the sinus tarsi are reviewed along with an analysis of ganglions. J Ultrasound.

They are the most common soft tissue mass in the hand and wrist. 520 E 70th St, New York NY, 10021. Bauer J, Mller D, Sauerschnig M et al. A developmental continuum between a true SC and GC of a synovial herniation followed by myxoid degeneration has even been theorized, but not confirmed [1, 6]. {"url":"/signup-modal-props.json?lang=us\u0026email="}, Weerakkody Y, Sriselvakumar S, Rasuli B, et al. Due to their strong similarities and their unclear pathogenesis, the scientific nomenclature associated with these lesions, labeled interchangeably in the literature, remains controversial. This space is medially continuous with the much narrower tarsal canal. 1 the There is a level of evidence of A for a GC/SC in the hip, the knee, and the ankle/foot, and of C in the wrist, with an overall strength of recommendation of 3 [9]. Steroid injection after aspiration does not seem to significantly improve the success rate of simple aspiration [16]. Upon palpation, a cyst can be soft or firm or movable or fixed. From the RSNA Refresher Courses. a tingling or burning sensation if the cyst is touching a nerve. Although typically small, large cysts with a long axis parallel to the length of the muscle, as the one illustrated in Fig. Despite the severity of artifact due to metallic hardware, it is still possible to appreciate its relationship to the medial gastrocnemius and the semimembranosus tendons. 2022 BioMed Central Ltd unless otherwise stated. Given their high prevalence, paralabral cysts deserve special mention. GCs may arise from the joint capsule, the ligaments, the tendon sheaths, the bursae, or the subchondral bone [1], being generally classified as juxta-articular, intra-articular or periosteal [2]. The main example, paralabral cysts, usually occurs in the setting of a superior or a posterosuperior labral tear, the cysts tending to extend into the suprascapular and the spinoglenoid notches, respectively, with resultant compression of the suprascapular nerve and subsequent denervation of the supra and infraspinatus muscles, or the infraspinatus muscle alone, if the site of compression is the spinoglenoid notch, distal to the branch to the supraspinatus [13, 14]. On the other hand, facet joint SCs tend to present at an extradural location, usually close to the joint [6], and have an average axial size of around 10mm [5, 6]. It has become the gold-standard modality in the characterization of periarticular cystic lesions, mainly due to its excellent soft-tissue contrast and extremely high diagnostic power [3]. Radiol Clin N Am 45:969982. 8. a, b. Bakers cyst in a 33-year-old man presenting with nonspecific intermittent knee pain. Sagittal FS PD-weighted MRI (a) shows diffuse hypodermic edema and a popliteal cyst with irregular and undefined margins in close relation to the medial gastrocnemius muscle and the semimembranosus tendon (arrow). As an example, while SC are very likely to occur around the knee and the hip, GC are most commonly found in the distal extremities, particularly in the wrist [1]. the contents of the sinus tarsi include the interosseous talocalcaneal ligament, cervical ligament, anterior portion of the subtalar joint capsule and synovium, posterior portion of the talocalcaneonavicular joint capsule and synovium, medial, inferior and lateral roots of the inferior extensor retinaculum and artery of the tarsal canal. A cortisone injection directed into the sinus tarsi can reduce inflammation and pain in some cases. Google Scholar, Apostolaki E, Davies AM, Evans N et al (2000) MR imaging of lumbar facet joint synovial cysts. Delayed arthrography, either by means of radiography, computed tomography, or MRI, 12h after intra-articular injection of water-soluble contrast agent, improves sensitivity of imaging in the demonstration of a cyst-joint communication, detectable in less than 50% on standard US or MRI [1]. Note the compression of the thecal sac, displaced posteriorly (arrow in b) and to the left side (arrow in a). Secondly, physiotherapy to improve the ankle's strength, balance, and mobility can reduce the load on the sinus tarsi. Manage cookies/Do not sell my data we use in the preference centre. 7. One of the major causes of Sinus tarsi syndrome is an inversion ankle sprain, where the foot twists inward; this is exaggerated over supination. In all patients, presenting with ganglia of the tarsal sinus, at least one other pathology was found at the ankle, that may be attributed to instability or deformation of the arch of the foot. doi:10.1016/j.spinee.2009.06.010, Orlandi D, Corazza A, Silvestri E et al (2014) US-guided procedures around the wrist and hand: How to do.

Osteoarthritis of the subtalar joint and intraosseous cysts may be present in advanced cases. Recommendations for rehabilitation include balance and proprioceptive training, and muscle strengthening exercises. Ligamentous injury and degeneration have been documented at this site 10 and may underlie sinus tarsi syndrome. Radiology 7. We'll gain an understanding of the best imaging strategies utilizing MRI to assess ankle pathology, and we'll develop a checklist approach to evaluation of MRI ankle pathology. 3. . After the knee, the hip is the second most-frequent joint where cystic lesions are more likely to consist of SCs rather than GCs, bursae being usually indistinguishable and also called SCs, as both are synovial-lined and may communicate with the joint, as previously mentioned [1, 17]. Imaging often demonstrates the ligaments and soft tissues in the sinus tarsi are injured. Axial FS PD-weighted MRI (a) shows a smooth, multiloculated, homogeneously hyperintense lesion located deep and medial to the radial artery (arrow) and lateral to the flexor pollicis longus (dashed arrow) and the flexor carpi radialis (arrowhead) tendons. Nevertheless, spontaneous resolution occurs in up to 50% of cases, and the main reason that patients seek medical evaluation is cosmetic concern, as symptoms are rarely significant [16]. Dean Taylor . 1. Ganglion cysts (GC) and synovial cysts (SC) are among the most frequently occuring benign cystic lesions in the joints. The preoperative recognition of these anatomical landmarks and the distinction between extra and intraneural cysts are crucial for the treatment outcome [20]. Ultrasound (US), as a low-cost, widely available modality, is the initial imaging method of choice for any palpable soft-tissue mass in the extremities, usually differentiating cystic from non-cystic ones [3, 8]. MRI can rule out other causes of shoulder pain. 2. Axial (a) and sagittal (b) T2-weighted images show a mildly hyperintense extradural rounded lesion (dashed arrows) arising from the right L4/L5 facet joint, which presents marked degenerative changes and fluid (asterisk). Several ankle ligaments ensure the static and dynamic stability of the ankle joint, but they are prone to injury due to acute trauma as well as repetitive ankle sprains. Eur Radiol 10:61523. doi:10.1007/s13244-013-0240-1, Article MRI is superior to US in the detection of smaller cysts and cyst-joint communications as well as associated disorders, such as acetabular labral tears and degenerative or inflammatory changes [17, 18].

Cardiology, Orthopedic Surgery 3 Providers. 28740-LT Arthrodesis, tarsal joint 8. It was first described by Denis O'Connorin 1958. [1] Ganglion cysts are round or oval fluid-filled lumps that develop on your tendons or in your joints in your wrists or hands, though they may also form on your ankles or feet. As previously mentioned, those with low-internal-signal intensity on the T2-WI are less likely to benefit from percutaneous rupture [5]. Sinus tarsi syndrome is the clinical syndrome of pain and tenderness of the lateral side of the hindfoot, between the ankle and the heel. Symptoms mainly arise from a compressive effect in adjacent structures and less frequently from inflammatory changes related to complication by rupture, hemorrhage, and/or infection [2, 6]. They communicate with the joint space and are typically multiloculated and small in size [19]. MRI MRI is probably the best test to show changes in the soft tissues of the sinus tarsi including inflammation, scar tissue formation or ligamentous injuries.

Privacy After closing the wound, the surgeon injected an ankle block using 30 cm3 of 0.5% plain marcaine. However, percutaneous image-guided procedures, including aspiration, with or without cyst rupture and/or steroid injection, are also effective alternatives that, despite the higher recurrence and failure rates, may avoid surgery without precluding it if warranted [3, 58]. 6. To a lesser extent, but not rarely, other bursae such as the obturator and the trochanteric bursae might also become enlarged, with anatomical location being the distinctive feature [18].

However, mainly due to its lower recurrence rate, surgical resection remains the gold-standard treatment option [8, 16], arthroscopy being a very promising alternative [16]. MR imaging of the tarsal sinus and canal: normal anatomy, pathologic findings, and features of the sinus tarsi syndrome After definition of the normal anatomic features of the tarsal sinus and canal at magnetic resonance (MR) imaging, 123 ankle MR imaging studies in 116 patients were reviewed. Besides cystic lesions in the sinus tarsi, there is also talocalcaneal fibrous coalition with surrounding marrow edema. Cystic lesions around the hip are incidentally found in up to 26% of asymptomatic patients during imaging studies [17]. ADVERTISEMENT: Supporters see fewer/no ads. Correspondence to A person with a ganglion cyst on their foot may have: a noticeable lump. Some ganglion cysts can occur in post-traumatic and post-surgical situations 12. Arthrography is invasive and relatively insensitive compared to MRI. Most cysts can be managed non operative with observation or aspiration. Thornburg L. Ganglions of the Hand and Wrist. {"url":"/signup-modal-props.json?lang=us\u0026email="}, Schubert R, Sinus tarsi ganglion cysts. The swelling can enlarge so that it can be mistaken for a cyst or tumor. Regardless of their distinction, most SCs and GCs on MRI look like smooth, well-circumscribed, and homogeneous cystic masses of variable size, with giant ones mainly occurring in large joints such as the knee and the shoulder [2] and being more prone to cause erosion of the adjacent bone [4]. Very small cysts may simulate a small effusion, but a clue to the diagnosis is the paucity of fluid in the remainder of the joint and the focal nature of the fluid. Sinus tarsi syndrome is a foot pathology, mostly following after a traumatic injury to the ankle. Degenerative joint disease is the main predisposing factor [16], but they might also be related to a number of other conditions such as trauma, rheumatoid arthritis, gout, and systemic lupus erythematosus [24]. SCs and GCs occur frequently but not necessarily in association with osteoarthritis. The objectives of this lecture will be to recognize MRI pathology of the ankle, including tendon, ligaments, inflammatory condition and nerve pathology. doi:10.1007/s003300050973, Article MRI is considered the best imaging modality for evaluation of the sinus tarsi and surrounding structures.

References 3 articles feature images from this case However, according to current evidence they are distinct, not only from an anatomopathological point of view, but also in their potential therapeutic approach [1]. As pointed out above, the radiologic distinction between an SC and a GC is frequently impossible, location being the most helpful criterion. 1. Injection with local anesthetic is diagnostic for localizing this problem to the sinus tarsi. At the foot and ankle, tarsal tunnel syndrome refers to a particular entrapment neuropathy that is caused by compression of the posterior tibial nerve along the medial aspect of the hindfoot. In this region, the posterior tibial nerve passes through a confined space, the tarsal tunnel or tarsal canal (Figure C). It sits between the talus and calcaneus (heel bone), an area known as the subtalar joint. doi:10.1016/j.ultrasmedbio.2012.04.006, Article Contrary to extraneural GC, which tend to present with a globular appearance, intraneural cysts are usually tubular lesions following the expected course of a nerve branch [20]. 1.

Absence of enhancement after gadolinium intravenous administration was confirmed in the same study (not shown). A proportion of patients have a history of trauma. The mechanism of cyst formation is similar to that of paralabral cysts in the shoulder, with the passage of synovial tissue and/or fluid to the adjacent soft tissues through a labral tear, the majority occurring in the anterosuperior part of the acetabular labrum [17, 19]. By definition, SCs are herniations of the synovial membrane through the capsule of a joint filled by synovial fluid, which may or may not keep a communication with the joint [14]. Regarding the optimal MRI quality in the study of this kind of lesion in the extremities, the smallest surface coil that covers the entire lesion should be chosen and an initial large field of view, including the contralateral side, followed by a smaller field of view targeted to the lesion, should be used. They usually do not cause any symptoms and often disappear on their own. Table 3 Reported indications for subtalar arthroscopy of the patients diagnosed with sinus tarsi syndrome. Although MRI is the gold-standard technique in characterizing cystic lesions in the knee [3], US is also highly accurate and provides guidance for percutaneous therapies[9]. Presentation Persistent pain for 4 weeks after an ankle inury. Among the fifteen normally occurring bursae around the hip, the iliopsoas bursa is the largest and the most constant, present bilaterally in 98% of adults [17]. Teh J & Whiteley G.

They tend to course with lateral recess stenosis and present dense adhesions to dura and nerve roots [6]. By using this website, you agree to our A ganglion cyst is a fluid-filled lump below the surface of the skin that appear on near joints and tendons. A giant synovial cyst incidentally found in the right hip of a 67-year-old woman during a routine computed tomography scan in the follow-up of a colorectal cancer in complete remission. It's cause is variable, and in some instances it may be caused by a space-occupying lesion compressing the tibial nerve. According to their cystic nature, the internal content of non-complicated GCs and SCs is typically hypo- to isointense on T1-weighted images (WI) and homogenously hyperintense on T2, PD, and STIR-WI, the degree of this hyperintensity being believed to vary inversely with the protein content of the fluid [2, 5, 6]. 2016;19(2):107-13.

Foot Ankle Int. Full size table. With an estimated prevalence of 19% in symptomatic patients having a MRI examination of the wrist and of 51% in non-symptomatic ones [15], GCs are the most common soft tissue tumors of the distal upper extremity, the great majority occurring in the dorsal aspect of the wrist according to most studies [16]. Am J Orthop 40:198201, Lowden CM, Attiah M, Garvin G (2005) The prevalence of wrist ganglia in an asymptomatic population: Magnetic resonance evaluation. Histologically, ganglia have a thin connective tissue capsule, but no true synovial lining, and contain mucinous material lled with gelatinous uid rich in hyaluronic acid and other mucopolysaccharides 4. The knee and the wrist are the most commonly involved joints, but their occurrence in other sites such as the facet joints, the shoulder, and the hip is not as rare as traditionally believed. CAS adjacent to the bone: periosteal ganglion cyst - rare and may occur more frequently in males 4, away from bone: soft tissue ganglion cyst, within the joint: intra-articular ganglion cyst, adjacent to a joint: juxta-articular ganglion cyst, within a peripheral nerve: intraneural ganglion cyst. Spine J 9:899904. The possibility of ganglions as a cause of sinus tarsi syndrome is supported by the case reports. The sinus tarsi is the cavity on the lateral (outer) side of the foot in front of the ankle. 45384-45385 . MGc, medial gastrocnemius. In fact, although relatively infrequent, the knee joint is also a known location for GCs, particularly intra-articular ones. 7. The cyst can range from the size of a pea to the size of a golf ball.

Often, muscle wasting is seen clearly on MRI, showing atrophy of the muscle and build-up of fat. 8. Their typical appearance on MRI consists of a smooth, well-circumscribed, thin-walled, homogeneous cystic lesion, not infrequently with an identifiable pedicle connecting to the joint. Eur Radiol 22(5):11408. The development of ganglion cysts may be rapid, or it may occur over many years. Articles.

Apply ice or cold therapy to reduce pain and inflammation. Ganglion cysts (GC) and synovial cysts (SC) are among the most frequently occuring benign cystic lesions in the joints. Unfallchirurg. Insights into Imaging doi:10.3174/ajnr.A3441, Article Although popliteal or Bakers cysts are not true SCs, in practical terms, they are considered similar for the same reason described above with regard to an iliopsoas bursa. Except for the spine, where zygoapophyseal or facet joint cysts frequently cause radiculopathy, neurogenic claudication, sensory deficits and, to a lesser extent, motor deficits [5, 6], most SCs and GCs in the extremities are asymptomatic and incidentally found by imaging performed for other reasons. These cysts can cause compression of the adjacent nerve fascicles, resulting in pain, paresthesias, weakness, muscle denervation, and atrophy [9]. Anesthesia 8.

Tendons: check the tendons using the four quadrant approach; Sagittal FS PD-WI shows an enlarged anterior cruciate ligament due to a multiloculated cystic lesion (arrows) embedded within its fibers. A stalk from the cyst led down to the sinus tarsi region. Due to their intramuscular location they are neither palpable at physical examination nor visible at surgery or arthroscopy [13]. Cysts in the lower mid talus are less frequent than in the calcaneus, but are also found adjacent to the ligament attachment. Radiology. Tenosynovial giant cell tumor (TSGCT) is a benign, solitary soft-tissue mass which is derived from synovial cells of the tendon sheath. Ganglion cysts are typically round or oval and are filled with a jellylike fluid. Besides bursitis, most periarticular cysts in the shoulder are associated with labrocapsular or rotator cuff tears resulting in the passage of fluid from the joint to the pericapsular soft tissues. 2000;20 Spec No(suppl_1):S153-79. doi:10.1016/j.ejrad.2014.03.029, Klauser AS, Tagliafico A, Allen GM et al (2012) Clinical indications for musculoskeletal US: A Delphi-based consensus paper of the European Society of Musculoskeletal Radiology.

Sagittal T2-weighted MRI (a) shows a slightly hyperintense cystic lesion posteriorly to the L3/L4 disc (arrow), as well as grade 1 degenerative spondylolisthesis at L4/L5. MRI- and surgical findings revealed that a ganglion was involved on one side (3.6%), and the other 27 sides were diagnosed with idiopathic TTS. Am J Roentgenol 170(6):15791583. J Ultrasound. Sinus tarsi is a small depression or cavity that is located between the talus (ankle bone that articulates with the tibia and fibula) and the calcaneus (heel bone), on the outer side of the ankle. Most patients are women in their sixties, usually presenting with chronic painful unilateral lumbar radiculopathy. PubMed MRI may be helpful to rule out accessory muscle or soft-tissue tumor Studies EMG positive finding include distal motor latencies of 7.0 msec or more prolonged SENSORY latencies of more than 2.3 msec sensory (SAP) more likely to be abnormal than motor decreased amplitude of motor action potentials of abductor hallucis or abductor digiti minimi Curr Rev Musculoskelet Med. Trauma is the most common cause following one single or a series of ankle sprains. The larger they are the more they are prone to present with internal heterogeneous content, as shown in Fig. Accurate distinction between benign and malignant soft-tissue masses, with estimated sensitivity and specificity of up to 95%, has been reported for distal upper extremity GCs [10]. Many demonstrate internal septations as well as acoustic enhancement 5. 7, so as to complicate by rupture with resultant inflammation of the surrounding soft tissues, as illustrated in Fig. Besides the general risk factors for the development of intra- and periarticular cysts described for other joints, such as osteoarthritis, some other knee-specific disorders include meniscal and cruciate ligament lesions [2]. Sinus tarsi ganglion cysts Case contributed by Dr Roberto Schubert Diagnosis certain Edit case Share Add to Citation, DOI and case data Presentation Persistent pain for 4 weeks after an ankle inury. As shown in Fig. Surgical excision of symptomatic, soft-tissue cystic lesions of this type, arthroscopic when possible, has been the advocated treatment so far, with satisfactory results. These lesions are seldom reported in the cervical spine and are even rarer in the thoracic spine. Rosenberg Z, Beltran J, Bencardino J. The joint most commonly affected by SCs is the knee. 3, occasionally occur. Sinus Tarsi Syndrome : MRI. CAS 2. Results Altogether, 31 MRIs demonstrated fluid extending from the sinus tarsi along the frondiform ligament toward the EDL. Degenerative joint disease is the main predisposing factor [1-6], but they might also be related to a number of other conditions such as trauma, rheumatoid arthritis, gout, and systemic lupus erythematosus [2-4].Due to their strong similarities and their unclear .

The existing treatment strategy is controversial; however, surgical . Axial MRI of a ganglion cyst. Besides cystic lesions in the sinus tarsi, there is also talocalcaneal fibrous coalition with surrounding marrow edema. In a search of medical records, signal alterations of the tarsal sinus consistent with ganglia were retrospectively identified in 34 of 969 ankle MR examinations, performed at our institution between 2004 and . Radiographics. Sinus tarsi syndrome is also referred to as sinus tarsitis. They can cause a myriad of symptoms depending on location due to mass effect on adjacent structures, and these are best discussed under location-specific subsites.

Less than 25% of GCs of the wrist occur in the volar aspect, as the one presented in Fig. PubMed Intraosseous GCs typically occur in the epiphyseal-metaphyseal region of long bones, the proximal tibia being the most frequently reported location within the knee [1, 2]. The sinus tarsi space is filled with many connective tissues that contribute to the stability and the proprioception of the ankle (proprioception is the unconscious perception of movement and spatial orientation arising from stimuli within the body itself). The cyst itself may show diffuse enhancement after intravenous administration of gadolinium contrast, but there is often an absence of enhancement of the pericapsular soft tissue edema. US-guided aspiration is an effective procedure when treatment is required, reducing patient discomfort and the risk of damage to adjacent structures when compared to the non-guided technique [8], as well as avoiding the potential risks of surgery [16].

MRI was performed in two cadaveric ankles following injection of the sinus tarsi and EDL tendon sheath, under ultrasound guidance. Springer Nature. Ligaments: check the syndesmosis, the lateral and medial ligaments. The site of origin of the cyst is more evident on the sagittal T2-weighted MRI (b), which seems to originate more distally in the radioscaphoid interval (arrow). Overall, an MRI scan will clearly show the ganglion cyst in the shoulder and whether it compresses the nerve. A special ankle brace for sinus tarsi syndrome can be pretty helpful. PubMedGoogle Scholar. Recent data suggest that the magnetic resonance imaging (MRI) features of SCs might help in the selection of patients who may benefit the most from nonsurgical intervention as a first treatment option, with T2-hyperintensity predicting a better outcome, probably due to the lower viscosity of their content making them easier to rupture [5]. The axial view (b) clearly demonstrates the extradural location of the lesion (dashed arrow) arising from the left L3/L4 degenerated facet joint, which presents synovial effusion (asterisk). The lesion lies lateral to the sinus tarsi (asterisk), likely arising from the cervical ligament. The lesion, probably corresponding to an enlarged iliopsoas bursa, displaces anteromedialy the iliopsoas muscle, and despite its close contact with the iliac bone, any erosion is seen. Nevertheless, depending on their age, anatomic location, and eventual complication, they might have many distinct appearances, including septae and internal debris, which the radiologist must be familiar with in order to accurately differentiate them from worrisome cystic-like lesions. Steven P. Meyers. Figures 3 and 4 show the pre-operative MRI images of the ganglion cyst indication causing sinus tarsi syndrome. . Swelling over the hollow between the ankle bone and the heel bone can develop. The patient received a modified Jones dressing.
