Reason: rule out SL ligament injury and possible occult ganglion cyst History: pain with range of motion over SL dorsally LIGAMENTS: No intra-articular gadolinium is identified within the radiocarpal joint. The scapholunate and lunotriquetral ligaments appear intact. There is a lobulated focus of fluid signal intensity along the volar aspect of the radioscaphocapitate ligament which likely represents ganglion formation measuring 8 x 3 x 10 mm (image 10; series 601).TRIANGULAR FIBROCARTILAGE COMPLEX: There is heterogeneity and intermediate signal intensity within the triangular fibrocartilage complex at the level of the foveal attachment which may reflect minimal degeneration. There is a lobulated focus of fluid signal intensity along the volar aspect of the triangular fibrocartilage and ulnar styloid measuring approximately 9 x 7 x 8 mm which likely represents ganglion formation (image 5; series 501). The ulnar styloid and foveal attachment of the triangular fibrocartilage appear intact. There is no significant fluid within the distal radioulnar joint.TENDONS: The flexor and extensor tendons appear intact. BONES: No bone marrow signal abnormality is identified.
1. No evidence of scapholunate or lunotriquetral ligament injury.2. Lobulated focus of fluid signal intensity along the volar aspect of the triangular fibrocartilage complex likely representing ganglion formation.3. Lobulated focus of fluid signal intensity along the volar aspect of the radioscaphocapitate ligament also likely represents ganglion formation.
