title: Right internal iliac vein joining the left common iliac vein: case report demonstrated by CT angiography.
abstract: An unusual variation of the iliac veins was detected by computed tomography (CT) angiography in a 35-year-old man. In coronal CT reconstructions, it was shown that the right internal iliac vein of this patient crossed to the left side and drained to the left common iliac vein. This variation is important in retroperitoneal, laparoscopic and orthopedic surgery. We present the CT findings and discuss the embryological origin of this unusual congenital anomaly.
