[A case of carpal tunnel syndrome caused by a ganglion cyst--diagnosis and follow-up study with magnetic resonance imaging].
We report a case of carpal tunnel syndrome (CTS) caused by a ganglion cyst which was diagnosed by magnetic resonance (MR) imaging of the left wrist. MR images depicted a 10-mm ganglion cyst which pressed the median nerve toward the ulnar side. The ganglion cyst was punctured under direct endoscopic visualization in the carpal canal, subsequently the clinical and the electrophysiologic findings of CTS improved. The median nerve was delineated in its proper position. MR imaging of the wrist, a noninvasive means to observe median nerve, is useful for the diagnosis and the follow-up study of CTS.
