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.
Other signs useful in identifying intussusception include:
- target sign (doughnut sign)
- crescent in a doughnut sign
