The pseudokidney sign is a characteristic ultrasound appearance in some cases of intestinal intussusception. It refers to the longitudinal ultrasound appearance of the intussuscepted segment of bowel which mimics a kidney.
The fat-containing mesentery, containing vessels, which is dragged into the intussusception, is reminiscent of the renal hilum, with the renal parenchyma formed by the edematous bowel.
