Crossed fused renal ectopia

Case contributed by Dr Varun Babu

Presentation

Dysphagia and vomiting.

Patient Data

Age: 40 years
Gender: Female
Modality: CT

Arrested ascent of right kidney with superior border reaching only the L2 vertebra. Ectopic left kidney is seen to the right of midline and fused to the medial aspect of right kidney. Malrotated right kidney with hilum pointing anterolaterally.

Both kidneys have an extra renal pelvis. Normal left ureter insertion.

Origin of renal vessels from abdominal aorta is beneath the inferior mesenteric artery with left kidney receiving dual arterial supply - renal branch and right common iliac arterial branch. 

Case Discussion

This patient came for low back ache evaluation under MRI and the absence of right kidney in it's normal position accompanied by an empty left renal fossa, prompted further evaluation. Whilst the CT abdomen was done for different purposes all together, this anatomic variant was confirmed.
