Pain. TFCC tear? LIGAMENTS: The scapholunate and lunotriquetral ligaments appear intact. A subcentimeter lobulated focus of fluid signal intensity immediately dorsal to the scapholunate ligament likely represents a ganglion.TRIANGULAR FIBROCARTILAGE COMPLEX: There is intermediate signal intensity within the articular disc of the triangular fibrocartilage just radial to the lamina suggesting degeneration; I see no fluid signal intensity traversing the articular disc to indicate a tear.TENDONS: There is dislocation of the extensor carpi ulnaris tendon such that the tendon courses volar to the ulnar styloid; there is little if any edema in the adjacent soft tissue, so I suspect this is a chronic abnormality. The remaining tendons are unremarkable. BONES: Bone marrow signal intensity is within normal limits.ADDITIONAL
1.Dislocation of the extensor carpi ulnaris tendon volar to the ulnar styloid.2.Intrasubstance degeneration of the articular disc of the triangular fibrocartilage without discrete tear.3.Ganglion dorsal to the scapholunate ligament.
