Fibroma of tendon sheath extending to the radiocarpal joint with median nerve compression: A case report.

ABSTRACT:

Rationale

Fibroma of tendon sheath (FTS) is a rare benign tumor arising from the synovial membrane of the tendon sheath. It seldom causes peripheral nerve compression or extends into a synovial joint. We report an unusual case of FTS within the radiocarpal joint, compressing the median nerve and leading to secondary changes in the radius and scapholunate joint.

Patient concerns

A 59-year-old woman presented with a 2-year history of a progressively enlarging, tender mass on the volar aspect of her right wrist. She exhibited positive Tinel's sign and Phalen's test. Magnetic resonance imaging revealed a hypointense mass on T1-weighted images and a heterogeneously hyperintense mass on T2-weighted images, extending into the radiocarpal joint.
