case_images: A CT of the abdomen and pelvis with contrast showed diffuse colopathy of the sigmoid colon with a large amount of extraluminal air and fluid in the left retroperitoneum, tracking through the left perirenal space into the left upper quadrant abdomen as seen in Figure 1. While bowel perforations are considered intraperitoneal in nature, our patient developed subcutaneous emphysema secondary to a bowel perforation, explaining the retroperitoneal findings seen in Figure 1.
