Intraneural ganglilon of superficial peroneal nerve was rare condition around foot and ankle. we experienced a case of recurred intraneural ganglion of superficial peroneal nerve on foot. We treated the case with idendify of intraarticular branch of ganglion. We report the case with a review of literature.

Purpose: Pathogenesis of intraneural ganglion is controversial, however, the synovial theory that the intraarticular region is the origination of disease has come into the spotlight nowadays. But there are a few researches about intraneural ganglion in foot and ankle. We studied 7cases of intraneural ganglion. We are going to prove the synovial theory by indentifying articular branch of intraneural ganglion. Materials and Methods: From August 2003 to May 2011, we evaluated 7 ouf of 8 patients diagnosed as a intraneural ganglion in foot and ankle. The gender ratio were 4 male and 3 female, and the mean age at the time of surgery was 52.9 years. Clinically, we checked pre and post operative symptom, muscle tone and whether loss of muscle tone and sensation exists. We analyzed surgical records and preoperative MRI and compared those with intra-operative finding. Results: In MRI analysis of 7cases, the connection around the joints were confirmed, and 1 case was confirmed in the retrospective analysis of MRI. Intraneural ganglions occurred in medial plantar nerve 3 cases, lateral plantar nerve 1 case, superficial peroneal nerve 1 case and sural nerve 1 case. We could not found recurrence during the follow up periods. Most patients relieved pain after operation, but recovery of sensation was unsatisfactory. We could find some cases pathological finding of the nerve intraoperatively, and clinical result of that cases was poor. Conclusion: Intraneural ganglion can occur in various parts in foot and ankle. We concluded that the intranneural ganglion originated from joint by identifying the artichlar branch of ganglion. Due to its small size, it is difficult to find articular branch in operation field. But we do our best to find and remove articular branch. Currently, considering the small amount of research in foot and ankle, more research about articular brach is needed.

There are a few reports on tarsal tunnel syndrome resulting from the intraneural ganglion. Although it can occur through a connection with the adjacent joint, there is no consensus on its pathogenesis and treatment method. This paper reports a case of tarsal tunnel syndrome resulting from the intraneural ganglion of the medial plantar nerve of the tibial nerve.

An intraneural ganglion in the peripheral nerve and the resulting ulnar neuropathy at the elbow are uncommon and may show various symptoms ranging from local pain to motor and sensory impairment. We report a case of a 76-year-old man who was diagnosed with ulnar neuropathy caused by an intraneural ganglion derived from the elbow. We also discuss the pathophysiology, treatment, prognosis, and diagnostic value of ultrasonography in neuropathy caused by a ganglion.

Intraneural ganglia in the upper extremity are rare, and the involvement of the digital nerve of hand has not been reported. The following case report demonstrates a 57-year-old woman with a symptomatic nodular mass on the thenar area of the left hand. Magnetic resonance images showed a lobulated, homogeneous mass of high signal intensity on T2-weighted images and low signal intensity with peripheral enhancement on T1-weighted images. Excisional biopsy and histopathologic examination revealed an intraneural ganglion of the digital nerve of the thumb. Her symptom disappeared immediately after the surgery, and has remained free of abnormal sensation and parestheia for the 3-year follow-up period.

A case of a peroneal nerve palsy caused by repeatedly recurred intraneural ganglion cyst is presented. A 19 year old male suffered from tingling sensation on the foot dorsum more than one year and underwent two times of mass excision and nerve palsy was recorvered. But it was recurred once more after 10 months after the second excision. The mass was located in the fibro-osseous tunnel against the fibular neck and the origin of the peroneus longus. The third complete excision was done and full recovery was obtained in 6 months.

Ganglion cysts occurring within sheaths of peripheral nerves have been documented, but are relatively rare entities. The peroneal nerve at the level of the knee and proximal tibiofibular joint is most commonly involved. We report a case of the intraneural ganglion cyst in the peroneal nerve without neurologic deficit, which was excised sucessfully.

Ganglion cysts that occurred within sheaths of peripheral nerves have been documented in literatures, but it is relatively rare condition. The peroneal nerve is the most common site of involvement. Other reported sites of involvement are the radial, ulnar, median, sciatic, tibial and posterior interosseous nerves. We report a case of the intraneual ganglion cyst within peroneal nerve and another case of the intraneural ganglion cyst within a medial plantar nerve that were successfully excised without neurologic complication.

Purpose: Ganglion cysts of peripheral nerve are uncommon. Ganglion cysts located within the nerve and extraneural ganglia that cause symptomatic nerve compression have been reported. We report an unusual case of epineural ganglion cyst confined to the epineurium of the sural nerve at the foot. Methods: A 45-year-old woman was referred because of a mass on the foot. She had six months' history of pain and numbness in the right small toe. During the examination of the lesion, multinodular cystic mass was identified arising from the epineurium of the sural nerve. The nerve fascicles were compressed by the cyst, but the cyst wall clearly did not invade the fascicle. With the aid of surgical microscope, the epineural cyst was completely excised along with epineural tissue to which it was attached, and the sural nerve was decompressed. There was no relationship between the cyst and either the joint capsule or tendon sheath. Since the cyst was on the periphery of the nerve it was possible to remove the cyst intact without damaging the underlying fascicles. Results: The postoperative course was uneventful. Pathologic examination showed a ganglion cyst with a degenerated collagen fibers and contained a yellowish, jelly-like mucinous substance. No neural elements were identified within the cystic wall. Her sensory impairment improved progressively. At the 15 months follow-up, she was asymptomatic with no neurological deficits. Conclusion: Rarely, ganglion cysts can involve peripheral nerves, leading to varing degrees of neurological deficits. Intraneural intrafascicular ganglion may be difficult to separate from the neural elements without nerve injury. Epineural ganglion, subcategorized as intraneural extrafascicular ganglion, can be removed without damage to the underlying nerve.
