Gas in midfoot. Evaluate for infection. There are chronic appearing changes in the cuboid and lateral cuneiform at the joint line. There is no cortical destruction or evidence of osteomyelitis. Scattered foci of signal void are compatible with gas as seen on prior CT.There is skin thickening and edema particularly affecting the dorsolateral aspect of the mid and forefoot. There is also extensive increased signal affecting the muscles of the foot consistent with edema. No discrete drainable fluid collection is identified. The ligaments and tendons of the ankle appear intact.
1. Extensive edema of ankle and midfoot without specific evidence of osteomyelitis. Gas is again noted adjacent to multiple bones in the foot. No drainable fluid collection is identified.2. Signal abnormality within the medial cuboid/lateral cuneiform is likely degenerative in etiology or post-traumatic, infection is considered less likely.
