A case report of left sided IVC with retroaortic right renal vein and hemiazygos continuation.

A case report of a left sided IVC with hemiazygos continuation and retro aortic right renal vein in a 45 year old female is described here with discussion of embryogenesis of this anomaly and its clinical importance. The anomaly was first observed on computer tomographic images performed for a different purpose. Doppler ultrasound done afterwards then showed absence of hepatic segment of the IVC and a retro aortic right renal vein. As far as our search is concerned this is the first report of its kind in Ethiopia.
