Signs of ileus are present: small bowel is dilated with gas-fluid levels. The underlying cause can be identified, as transitional zone is seen in the terminal ileum, which shows thickened wall and blurred surrounding fat tissue. Most likely, postoperative fibrous adhesions have caused small bowel obstruction. Free fluid is seen in the pelvis. Note the intestinal malrotation, with colon predominately within the left hemiabdomen.
Ectopic kidneys can be seen: left between spleen and diaphragm, and right between liver and diaphragm.

The patient underwent urgent surgery and bowel obstruction due to adhesions was confirmed.
While the typical presentation of ileus due to postoperative adhesions is presented in this case, a less common case of ectopic kidneys is demonstrated. Subdiaphragmatic ectopic kidneys are an uncommon congenital anomaly, which is found once in 22 cases of ectopic kidneys1,2. It is most often discovered incidentally while being investigated for other pathology. Bowel malrotation is also present.
