To the Editor:—
The renal arteries typically arise between the midportion of the first lumbar vertebral body and the upper third of the second.1-4 Variations of approximately one vertebral body in either direction are well known. To the best of our knowledge, only one case of a single renal artery is reported arising above the level of the 12th thoracic vertebra,5 accompanied by a normal contralateral renal artery.
