Loop-to-loop colon

The loop-to-loop colon describes an abnormal colonic course associated with the absence of the left kidney from the renal fossa. 

The transverse colon extends to the lateral margin of the abdominal wall and the descending colon courses medially to fill the renal fossa, resulting in a "looped" colonic configuration on abdominal radiographs.

If colonic loops are seen in the renal fossa it should suggest the possibility of renal agenesis or ectopia.
