Male, 53 years old. Reason: r/o ganglion vs carpal boss History: dorsal wrist pain LIGAMENTS: Evaluation of the ligaments is limited by lack of intra-articular contrast. However, there is increased signal intensity traversing the membranous portion of the scapholunate ligament and extending into the dorsal fibers of the ligament, suspicious for tear. The lunotriquetral ligament appears intact.TRIANGULAR FIBROCARTILAGE COMPLEX: Although no fluid signal intensity is seen traversing the articular disc of the triangular fibrocartilage complex, a small linear focus of intermediate signal intensity partially traverses the articular disc just medial to its attachment to the radius, which is suspicious for tear, and likely spares the proximal fibers of the disc. There is also mild irregularity of the proximal surface of the triangular fibrocartilage more centrally which likely indicates partial tearing.TENDONS: The tendons appear unremarkable. BONES: There is slight bony prominence along the dorsal aspect of the capitate immediately proximal to the carpometacarpal joint and just medial to the extensor carpi radialis brevis tendon. Immediately distal to this bony prominence is a small ossicle (which may be bipartite) situated dorsal to the carpometacarpal joint, and measuring approximately 3.5 x 3 x 1.5 mm. This ossicle is evident on the lateral wrist radiograph from 02/19/2015. There is also an osteophyte/spur projecting from the ulnar aspect of the dorsal surface of the capitate, extending dorsal to the articulation between the bases of the third and fourth metacarpals.We see no ganglion. Small foci of signal abnormality within the bones of the proximal carpal row are of doubtful clinical significance.
1.Bony prominences along the dorsal surface of the capitate as well as a tiny ossicle dorsal to the third carpometacarpal joint. We see no ganglion.2.Findings suggestive of scapholunate ligament and triangular fibrocartilage tears as described above, the clinical significance of which is uncertain.
