Abstract

Ganglion cyst which originates from joint space can affect nearby nerves through an articular branch. Despite known as benign mucinous lesion, ganglion cyst can show significant fascicular invasion and expansion, resulting in compression neuropathy. Number of pathogenesis have been insisted but the most widely acknowledged one is synovial herniation hypothesis. It describes a capsular defect in joint and discharged fluid to aggregate as cyst along the epineurium of articular branch. Tarsal tunnel syndrome is an entrapment neuropathy of the tibial nerve or its branches in the tarsal tunnel of ankle. In this case report, we describe a case of ganglion cyst associated tarsal tunnel syndrome and its surgical treatment.
