Reason: synovitis without erosions . History: pain and swelling negative wrist x-ray LIGAMENTS: The scapholunate and lunotriquetral ligaments appear intact within the limitations of a non arthrogram examination.TRIANGULAR FIBROCARTILAGE COMPLEX: Motion artifact limits evaluation of the intrinsic ligaments and triangular fibrocartilage complex. There is increased signal abnormality and indistinctness of the ulnar aspect of the triangular fibrocartilage complex indicating erosion of the ulnar styloid and foveal attachments. TENDONS: There is circumferential fluid within the tendon sheath of the extensor carpi ulnaris as well as foci of low signal intensity debris indicating a tenosynovitis. The flexor and extensor tendons appear intact.BONES: There is a small erosion along the ulnar aspect of the triquetrum with associated increased bone marrow signal abnormality on fluid sensitive sequences. Otherwise no erosions are evident.ADDITIONAL
Findings consistent with the patient's known history of rheumatoid arthritis, including a small carpal bone erosion and synovitis, as described above.
