“…In another 4 cases, the findings were suggestive of joint connections to the STFJ, but no connection could be definitively confirmed given the limitations and number and quality of the available images. Based on our reinterpretation of these cases we found examples where intraneural cases were in fact extraneural; 5,87,101 cysts described as extraneural were thought to be intraneural; 41,42,53,59,92 2 cases that were unspecified appeared intraneural, 27,49 as did 1 case of an inflammatory pseudotumor;…”

615 Literature review J Neurosurg 125:615-630, 2016I ntraneural ganglion cysts are benign mucinous lesions that are formed within peripheral nerves and typically lead to symptoms and signs of peripheral neuropathy. Their pathogenesis has been controversial. Different treatments have been recommended. Outcomes have been disappointing and the recurrence rate high and underreported.Over the past 15 years, our group has provided substantial evidence to support a unifying articular (synovial) theory as the etiology for all intraneural ganglion cysts. In 2003, the senior author (R.J.S.) demonstrated that the prototypical intraneural cysts of the common peroneal nerve are joint derived. Cyst formation originates in the superior tibiofibular joint (STFJ) and propagates toward abbreviatioNs EMG = electromyography; NCS = nerve conduction studies; STFJ = superior tibiofibular joint. obJective The etiology of intraneural ganglion cysts has been controversial. In recent years, substantial evidence has been presented to support the articular (synovial) theory for their pathogenesis. The authors sought to 1) perform a systematic review of the world's literature on intraneural cysts, and 2) reinterpret available published MR images in articles by other authors to identify unrecognized joint connections. methods In Part 1, all cases were analyzed for demographic data, duration of symptoms, the presence of a history of trauma, whether electromyography or nerve conduction studies were performed, the type of imaging, surgical treatment, presence of a joint connection, intraneural cyst recurrence, and postoperative imaging. Two univariate analyses were completed: 1) to compare the proportion of intraneural ganglion cyst publications per decade and 2) to assess the number of recurrences from 1914 to 2003 compared with the years 2004-2015. Three multivariate regression models were used to identify risk factors for intraneural cyst recurrence. In Part 2, the authors analyzed all available published MR images and obtained MR images from selected cases in which joint connections were not identified by the original authors, specifically looking for unrecognized joint connections. Two univariate analyses were done: 1) to determine a possible association between the identification of a joint connection and obtaining an MRI and 2) to assess the number of joint connections reported from 1914 to 2003 compared with 2004 to 2015. resuLts In Part 1, 417 articles (645 patients) were selected for analysis. Joint connections were identified in 313 intraneural cysts (48%). Both intraneural ganglion cyst cases and cyst recurrences were more frequently reported since 2004 (statistically significant difference for both). There was a statistically significant association between cyst recurrence and percutaneous aspiration as well as failure to disconnect the articular branch or address the joint. In Part 2, the authors identified 43 examples of joint connections that initially went unrecognized: 27 based on their retrospective MR image reinterpretation o...

A ganglion cyst is the cystic lesion originates from the joint capsule or tendon sheath. This lesion is the most common soft tissue tumors of hand, wrist, and foot, and frequently observed in women between 30-50 years. A peroneal ganglion cyst is an uncommon lesion and rarely composes peroneal neuropathic symptoms. We report a 37-year-old man with swelling at the lateral portion of knee below, foot pain, loss of sensation at the lateral portion of left inferior cruris. Ultrasound (US) and magnetic resonance imaging (MRI) findings demonstrated a large cystic lesion in the peroneal muscle, and preliminary diagnosis of peroneal ganglion cyst was proved by cytology. The patient was asymptomatic one month after surgery. There was no evidence of residue or recurrence on US imaging after 6 months.

“…A direct X-ray is not useful in the diagnosis of ganglion cysts. However, it is helpful to show bone abnormalities and intraosseous lesions [9]. Upon X-ray, intraosseous ganglion cysts can be seen to be lytic, oval, or circular well-defined lesions in the subchondral area with or without cortical expansion or soft tissue expansion [4].…”

“…MRI can also show any deep extension of the foot dorsum ganglion through the intermetatarsal space [14]. Ganglion cysts are shown to be well-defined and hypointense on T1-Weighted (W) images ( Figure 4a) and hyperintense on T2-W images ( Figure 4b) [9]. Contrast enhancement can reveal septation and cyst walls in post-contrast images [9].…”

Soft tissue tumors of the foot and ankle are relatively rare and include tumor-like lesions and benign and malignant neoplasms. Only approximately 8% of all benign soft tissue lesions and 5% of malignant soft tissue tumors occur in this location [1]. Ganglion cysts are among the most common benign soft-tissue tumors in the foot and ankle [2]. They are often seen in women and younger adults [3]. They are most frequently located around the ankle or at the dorsum of the foot [1]. They are typically thin-walled and may be unilocular or multilocular. They contain a clear, gelatinous fluid [2]. Most of these
