51-year-old female with pain and swelling in the right index finger. Evaluate for tenosynovitis versus chronic fluid collection or osteomyelitis There is nonspecific soft tissue edema involving the index finger with slight thickening of the skin. There is edema and enhancement of the underlying subcutaneous fat. There is also enhancement of the nail bed. There are small foci of low signal intensity within the soft tissues along the radial aspect of the distal phalanx which are nonspecific but could represent small foreign bodies, which were not seen recent radiographs. Mild enhancement of the synovium of the flexor tendon apparatus is suggestive of mild tenosynovitis. There is mild enhancement of the synovium of the PIP joint of the index finger suggestive of mild synovitis, although we see no frank fluid within the joint. We see no frank fluid collection nor do we see bone marrow signal abnormality to suggest osteomyelitis.
Nonspecific inflammatory changes of the finger as described above. Small foci of low signal intensity within the soft tissues adjacent to the phalanx could represent foreign bodies but were not seen on recent radiographs and could also represent small foci of gas or small foci of hemosiderin from prior bleeding. We see no abscess or osteomyelitis.
