18-year-old female with wrist pain. Evaluate for TFC injury versus ECU tendinitis. LIGAMENTS: Evaluation of the intrinsic ligaments of the wrist is limited due to lack of intra-articular contrast. We see no tear of the lunotriquetral or scapholunate ligaments. TRIANGULAR FIBROCARTILAGE COMPLEX: We see no fluid signal intensity within the articular disc of the triangular fibrocartilage. There is intermediate signal intensity within the ulnar fibers of the triangular fibrocartilage that may reflect mild degeneration, however, we see no discrete tear. The meniscal homolog of the triangular fibrocartilage demonstrates mild diffuse increased signal intensity of uncertain significance.TENDONS: The tendons are normal in appearance.BONES: No bone marrow signal abnormality is identified.
Possible minimal degeneration of the fibers of the articular disc of the triangular fibrocartilage near the attachment to the ulnar styloid as well as mild increased signal intensity within the meniscal homolog of uncertain significance. We otherwise see no findings to account for the patient's pain.
