40-year-old male with swelling of wrist and fingers. There is reticulation of the subcutaneous fat of the dorsum of the hand and wrist, also extending along the ulnar aspect of the hand and wrist where it becomes confluent. Edema also extends into the bases of the fourth and fifth fingers. We see no abscess. There is however fluid within the tendon sheath of the extensor digitorum tendons, as well as synovial enhancement indicating tenosynovitis at the level of the wrist and proximal metacarpals. We see no findings to suggest osteomyelitis. There is mild enhancement surrounding the proximal interphalangeal joint of the middle finger, suggesting inflammation. We see no substantial joint effusion.
Soft tissue inflammation and extensor digitorum tenosynovitis.
