65-year-old woman with pressure ulcer of the sacrum, evaluate extent of wound. There has been suspected interval removal of the coccyx given an apparent osteotomy line, although destruction is not excluded. There is soft tissue irregularity with broad ulceration and gas extending to the sacrum, with abnormal signal intensity at the underlying distalmost segments of bone. The ulceration traverses nearly the width of the sacrum. There is enhancement of the soft tissues in this region, as well as of the distalmost osseous segments. Evaluation of the pelvis is otherwise within normal limits.
Ulceration with suspected partial surgical resection of the coccyx, and osteomyelitis of the distalmost sacral segments.
