1 Outside the Inside: A Review of Soft-Tissue Abnormalities Seen on Thoracoabdominal Computed Tomography  Susan J. Frank, MD, Shari Friedman, MD, Milana Flusberg, MD, Ellen L. Wolf, MD, Marjorie W. Stein, MD  Canadian Association of Radiologists Journal  Volume 65, Issue 4, Pages (November 2014) DOI: /j.carj Copyright © 2014 Canadian Association of Radiologists Terms and Conditions

2 Figure 1 (A) A 67-year-old woman after a ventral hernia repair with mesh (arrow). Axial noncontrast computed tomography (CT), demonstrating a large fluid collection with gas in the anterior abdominal wall typical of infection. (B) A 28-year-old man with sacral decubitus ulcer. Contrast-enhanced axial CT, demonstrating a large amount of gas within the gluteus muscles and subcutaneous inflammatory stranding typical for necrotizing fasciitis.

3 Figure 2 A 42-year-old man with pilonidal sinus disease. Axial noncontrast computed tomography, demonstrating a sinus tract (arrow) that extends from the midline, which does not communicate with the rectum.
