Abstract

Peroneal Intraneural Ganglion Cyst is a rare condition that only a few cases have been reported in the literature. A 55 years old middle aged Lady presented at our Outpatient Department with complaints of pain over lateral aspect of right knee and leg for the last 1 month. She also complained about the inability to extend the ankle and the toes for 1 week. No recent history of trauma was there. She has been complaining about tingling and Numbness over right foot for the last 1 month. Because of its radiological appearance and atypical clinical course, the lesion was diagnosed as Peroneal Intraneural ganglion Cyst. This 55 years old female patient, with no history of comorbidities, with above mentioned complaints, initially was managed elsewhere with conservative management. Referred to Orthopaedic surgeon for further management. After all necessary investigations, was planned for definitive management, which was Decompression of the Common peroneal nerve along with Neurolysis, Ganglion Cyst dissected and Disarticulation of proximal Tibio Fibular Joint.
