(A) Sagittal computed tomography image demonstrates cortical fragmentation of the plantar aspect of the calcaneus (arrows) and adjacent air and soft tissue ulceration.
(B) Corresponding fluid-sensitive short inversion time inversion recovery (STIR) image demonstrates extensive high-signal edema in the calcaneus (asterisk) and again demonstrates posterior plantar ulcer overlying the calcaneus (arrow).
