Reason: 64 yo woman with pain, swelling ulnar aspect of right hand/wrist. Dystrophic calcifications seen in soft tissue of right hand History: pain, swelling ulnar aspect of right hand/wrist There is degenerative subchondral cyst formation within the lunate and capitate bones. Note is made of a short fourth metacarpal. There is peripherally enhancing fluid within the ulnocarpal joint indicating a synovitis. There are multiple foci of decreased signal abnormality within the abductor digiti minimi muscle corresponding to the findings on recent radiographs which may reflect dystrophic calcification. There is enhancing signal abnormality within the abductor digiti minimi muscle at the level of the myotendinous junction indicating nonspecific inflammatory change. Although this examination was not optimized for evaluation of the triangular fibrocartilage complex, there is increased signal abnormality within the articular cartilage disc just proximal to its attachment on the ulnar styloid indicating degeneration or perhaps degenerative tearing. There is increased signal abnormality within the extensor carpi ulnaris tendon which may reflect a mild tendinosis. The flexor and chest with tendons appear intact. No additional bone marrow signal abnormality is identified.
1. Findings indicating a synovitis of the ulnocarpal articulation.2. Nonspecific inflammatory change within the abductor digiti minimi muscle at the level of the myotendinous junction.3. Punctate foci of decreased signal abnormality within the abductor digit minimi may represent dystrophic calcification.4. Short fourth metacarpal.
