A Case Report of Carpal Tunnel Syndrome Caused by Tripartite Ganglion of the Wrist Joint

Ganglion is not uncommon in the region of the hand. The authors experienced a case of carpal tunnel syndrome caused by a tripartite ganglion of the wrist joint, which occupied the hypothenar eminence, anatomical snuff box and ulnar side of the carpal tunnel. The median nerve palsy recovered favourably after extirpation of the ganglion and release of the transverse carpal ligament.While the ganglion resembled to a synovial cyst in rheumatoid arthritis, no evidence of rheumatoid arthritis was revealed by clinical and histopathological examinations. The carpal tunnel syndrome due to ganglion is well recognized, but it was scarcely documented, and a huge ganglion has not yet been reported in the literature.
