Male 27 years old Reason: TFCC tear History: wrist pain, instability. Numerous foci of signal void are noted in the soft tissues of the wrist particularly dorsally suggesting metallic susceptibility artifact related to prior surgery.TRIANGULAR FIBROCARTILAGE COMPLEX: We see no fluid signal intensity traversing the triangular fibrocartilage complex to indicate full thickness tear. There is thickening and increased signal intensity within both of the ulnar bands of the articular disk suggesting degeneration. There is also a small focus of abnormal signal intensity within the adjacent subchondral marrow of the distal ulna which is likely degenerative in etiology and overall the findings are similar to outside hospital MRI of 2013.LIGAMENTS: Evaluation of the intrinsic ligaments of the wrist is limited due to lack of intra-articular contrast. There is a small lobulated collection of near fluid signal intensity along the dorsal margin of the scapholunate ligament suggestive of a small ganglion but we otherwise see no specific findings to suggest tear of the scapholunate or lunotriquetral ligaments.TENDONS: The tendons appear normal. BONES: There is a focus of edema type signal within the ulnar and proximal aspect of the lunate bone volarly which is new compared to prior study. A small cystlike focus of abnormal signal is noted within the proximal triquetrum. These findings and nonspecific and we see no gross overlying cartilage defects. The remainder of the bone marrow signal is normal.
1. Findings suggestive of degeneration of the ulnar fibers of the articular disk of the triangular fibrocartilage complex but no discrete fluid filled tear.2. Small foci of bone marrow signal intensity as described above could reflect sequela of ulnar abutment but we see no discrete tear of the radial aspect of the triangular fibrocartilage complex nor do we see any articular cartilage defects.
