Reason: evaluate for tenosynovitis of L wrist History: L wrist swelling and pain along extensor tendons A marker was placed along the dorsal aspect of the wrist. Deep to the marker, we see fluid surrounding the extensor digitorum tendons of compartment 4, compatible with the suspected clinical history of tenosynovitis. There is also mild increased signal intensity within the tendons themselves suggesting tendinosis/inflammation. There are multiple slips of the extensor pollicis longus, a normal anatomic variant. The remaining extensor tendons appear intact. The flexor tendons appear intact. There is a tiny focus of increased signal intensity within the dorsal fibers of the scapholunate ligament which may represent a small perforation of questionable significance. The ligament otherwise appears intact given the limitations of a non arthrogram study. The lunotriquetral ligament is not optimally visualized but we see no findings to suggest disruption. The triangular fibrocartilage complex appears intact within the limitations of a non arthrogram study. There is a suture line along the volar skin surface the wrist with low signal intensity within the underlying subcutaneous fat compatible with scarring. There is discontinuity of the flexor retinaculum compatible with carpal tunnel release. There is a small 6 mm lobulated collection of fluid signal intensity within the soft tissues dorsal to the scaphoid near the attachment of the dorsal intercarpal ligament which likely represents a small ganglion. Mild osteoarthritis affects the basilar joint. There is a small focus of edema type signal abnormality in the distal diaphysis of the first metacarpal of uncertain significance.
Extensor digitorum tenosynovitis concentrated dorsal to the distal carpal row and other findings as described above.
