Lee and Cho: Sensory Neuropathy of the Common Palmar Digital Nerve Caused by Ganglion Cyst

Abstract

Ganglion cysts that arise from the palm and compress the median nerve are rarely reported. Previous studies have described ganglion cysts compressing the motor branch of the median nerve, but no reports have described sensory neuropathy of the common palmar digital nerve as a result of ganglion cysts. We present a case of sensory neuropathy similar to carpal tunnel syndrome caused by a ganglion cyst that originated from the second carpometacarpal joint.
