Carpal Tunnel Syndrome Caused by a Simple Ganglion

Abstract

The compression of peripheral nerves by simple ganglia is a well recognized and documented clinical entity. It has been reported where ganglia have been associated with the ankle, knee and elbow joints (D. M. Brooks, 1952). It is probably best known in compression of the deep branch of the ulnar nerve in the wrist, first described by Seddon (Seddon H. J. 1952). Median nerve compression at the wrist, however, that causes a carpal tunnel syndrome would appear to be well recognized but poorly documented. Brooks (1952) described a case and until now, no others have been recorded in the literature. This case report describes such median nerve involvement with some interesting features.
