CT Demonstration of the Extensive Extension of the Emphysematous Gangrene of the Lower Extremity Extending tothe Body: A Case Report

Emphysematous gangrene of the lower extremity in a diabetic patient due to minor trauma is being presented. The gas originating from the extremity extended along to fascial planes into the pelvic cavity, scrotal region, retroperitoneal space, and abdominal wall. CT demonstrated the pathways of upward extension of emphysematousgangrene. Anatomic pathways of the spread of the disease are insertions of the iliopsoas, piriformis and obturator internus muscles, and their fascial investments, and the endopelvic fascia. Anatomic pathways on CT and the roleof CT are discussed.
