Recurrent carpal tunnel syndrome following release in December 2015 Tendons: The extensor tendons are intact. The flexor tendons are intact. There is no tenosynovitis.Ligaments: The scapholunate ligament is intact. The lunotriquetral ligament is intact. The triangular fibrocartilage complex is intact.Bones/joints: There is no dislocation or subluxation and there is mild negative ulnar variance. There is no joint effusion. Cystic changes are identified within the distal radioulnar joint with additional mild osteoarthritic changes of the lunate and proximal carpal row. Otherwise the marrow signal of the wrist is normal.Muscles: There is no muscle tear or atrophy of the flexor or extensor compartments.Nerves: The level of the radiocarpal joint, the median nerve demonstrates a normal morphology. Between the levels of the distal radioulnar joint and the hook of the hamate there is a T2 hyperintense lesion measuring 8 x 3 x 9 mm demonstrating mild enhancement following contrast administration. This focus is contiguous with and distorts the ulnar aspect of the median nerve.
Abnormal morphology of the median nerve with a mildly enhancing lesion identified along the ulnar aspect of the nerve between the distal radioulnar joint and the hamate concerning for scar formation.
