47-year-old male with prior imaging showing 2 collections of gas, one possibly more proximal than ulcer on exam. Evaluate for soft tissue abscess. Diffuse soft tissue swelling within the subcutaneous tissues and musculature of the foot with skin ulceration along the plantar aspect overlying the second and third metacarpal heads and an adjacent collection containing foci of low signal intensity likely gas. There are several small focal collections along the plantar soft tissues which demonstrate rim enhancement suspicious for small abscesses, for example a small collection adjacent to the first metacarpal head measures 12 mm x 6 mm (series 1201, image 56) and an additional collection more laterally overlying the plantar aspect of the third metacarpal head measures 13 mm x 8 mm (series 1201, image 56). There is suggestion of decreased T1 signal intensity affecting the sesamoid bones about the first metacarpal head with no corresponding increased STIR signal or enhancement. The remaining bones of the foot demonstrate normal bone marrow signal intensity.
Diffuse soft tissue swelling with a focal area of ulceration along the plantar aspect of the foot with suspicion for small abscesses as described above. No findings to suggest osteomyelitis.
