Bilateral malrotated kidney with major venous variant: a cadaver case report

Introduction Congenital anomalies of the kidney exhibit great variety. The major anomalies are fused kidney, ectopic kidney, and malrotated kidney [1]. Because many affected patients are asymptomatic, some anomalies are incidentally found by computed tomography and others are found after death. Recent popularization of kidney transplantation requests has led to an increase in research of the vascular anatomy in patients with many kinds of kidney anomalies. In particular, the right common iliac vein is a very important vessel for angiostomy. Moreover, rotational anomalies of the kidney definitely affect the vascular structure. We herein report a case of bilateral malrotated kidneys with a variation of the common iliac vein found during a gross anatomical dissection course for students in 2015.
