Abstract

Guyon's canal syndrome is a compression neuropathy of the ulnar nerve entrapment at the wrist. Compression of the ulnar nerve at the wrist by a ganglion, lipomas, diseases of the ulnar artery, fractures of the hamate and trauma is a common etiological factor. We report on a rare case of ulnar neuropathy caused by a schwannoma at the level of Guyon's canal.
