Pneumoretroperitoneum – presence of gas within the retroperitoneal space. Typically the air outlines structures like the kidneys, psoas muscles and retroperitoneal portions of the bowel (duodenum, ascending colon, descending colon and rectum). It is almost always due to perforation of a hollow retroperitoneal viscus such as may occur in duodenal ulcer disease, abdominal trauma, diverticulitis, ischemic colitis, colorectal cancer and following endoscopy. Residual air from urological or spinal surgery is another possible cause.
