FINDINGS

AP and oblique radiographs of the right foot (Figs. 100A and 100B) demonstrate soft tissue edema and subcutaneous gas in the soft tissues about the first metatarsophalangeal (MTP) joint, which also tracks along the first and second metatarsals. The oblique view demonstrates a soft tissue defect subjacent to the first MTP joint. Axial CT of the right foot (Fig. 100C) at the level of the metatarsal heads reveals soft tissue gas about the first MTP joint with an associated superficial cutaneous defect.

DIFFERENTIAL DIAGNOSIS

Gas-forming soft tissue infection, recent debridement, penetrating trauma, osteomyelitis.

DIAGNOSIS

Soft tissue infection with gas-forming organism.
