60 year-old female, with peripheral vascular disease status post left above-the-knee amputation with open wound and left leg edema. Evaluate for fluid collection, tracking air.IMAGE ACQUISITIONS: Non-IV contrast enhanced CT of the pelvis and both thighs. Lack of IV contrast decreases the ability to detect small abscesses.Patient is status post left above-the-knee amputation. Irregularity of the soft tissues of the distal end of the remaining left thigh is compatible with the stated history of open wound, and there several small pockets of gas density seen within the soft tissues surrounding and adjacent to the amputated distal left femur. There are no specific features of osteomyelitis on this study, although MRI would provide a more sensitive assessment for osteomyelitis. No abscess is identified within the left thigh. Air does not extend into the proximal thigh.There is moderate bilateral stranding of the subcutaneous fat of the thighs compatible with edema, which extends into the subcutaneous fat of the pelvis and lower abdomen. An intramedullary rod is present in the right femur and results in metallic artifact that slightly limits the exam of the surrounding anatomic structures. There are atherosclerotic calcifications seen within the pelvis and both thighs as well as a femoral artery stent on the right.
Status post left above-the-knee amputation with stump wound and small foci of air immediately adjacent to the distal left femur. No abscess evident.
