Pain. Carpal abutment with possible TFCC tear. LIGAMENTS: The lunotriquetral and scapholunate ligaments appear intact. No contrast is noted within the midcarpal joint space.TRIANGULAR FIBROCARTILAGE COMPLEX: There is mild intermediate signal intensity within the ulnar fibers and lamina of the articular disc of the triangular fibrocartilage which may reflect focal degeneration or synovitis, but this is equivocal, and I see no gadolinium traversing the disc to indicate a tear. No gadolinium is noted within the distal radioulnar joint. Gadolinium does extend from the radiocarpal joint proximally along the medial aspect of the distal ulna volar to the extensor carpi ulnaris tendon, which could represent disruption of the medial capsular structures, but the clinical significance of this finding is uncertain.TENDONS: There is a longitudinal split of the extensor carpi ulnaris tendon distal to the ulnar styloid. The tendon otherwise appears normal, without fluid in the sheath, and hence this may represent a normal variant. The remaining tendons appear normal. BONES: The bones of the wrist appear normal.
Possible mild focal degeneration/synovitis of the ulnar fibers and lamina of the articular disc of the triangular fibrocartilage, but this is equivocal and no fluid-filled tear is evident. Gadolinium extending from the radiocarpal joint proximally along the medial aspect of the ulna could represent a defect in the medial capsular structures, but is of uncertain clinical significance.
