20-year-old male with wrist pain. LIGAMENTS: Intra-articular contrast is identified within both the midcarpal and radiocarpal joints. Intra-articular contrast traverses the scapholunate ligament indicating a tear. The lunotriquetral ligament appears intact.TRIANGULAR FIBROCARTILAGE COMPLEX: The triangular fibrocartilage complex appears intact. No intra-articular contrast is identified within the distal radioulnar joint.TENDONS: The flexor and extensor tendons appear intact. BONES: There is increased bone marrow signal abnormality on fluid sensitive sequences within the triquetrum which may represent a direct bone contusion. No linear signal abnormality is identified to suggest an acute fracture.ADDITIONAL
1. Findings consistent with disruption of the scapholunate ligament as described above. The triangular fibrocartilage complex appears intact.2. Bone contusion of the triquetrum.
