Thoracic Origin of Single Right Renal Artery: Some Interesting Facets

Abstract

Two cases of thoracic origin of the right renal artery, arising from the level of D11 vertebrae detected on an incidental computed tomography examination are reported. A brief review of embryology is presented. Simultaneous variation of the origin of the right inferior phrenic artery is highlighted as a unique feature of our cases. The importance of this relatively uncommon anomaly in the clinical context is discussed.
