A Very Low-Positioned Aortic Bifurcation

ABSTRACT

Anomalies of the aortoiliac arteries are rarely reported and are generally discovered incidentally on imaging performed mostly for investigation of other medical concerns. While aortic bifurcation is typically reported at the fourth lumbar vertebra, variations are possible. We present a case with very low aortic bifurcation, almost at the level of S2, with various other anomalies including a corkscrew left common iliac artery passing just anterior to the bladder dome with pulsation noted during cystoscopy. An ectopic right kidney was also noted. To our knowledge, these vascular anomalies have not been reported previously.
