Bilateral renal artery aneurysm rupture in a man with leukemia: report of a case.

Renal artery aneurysms, once thought to be rare, are diagnosed more frequently due to the increasing use of computed tomography, angiography, and other imaging to delineate pathology. The incidence is less than 1% in the general population,(1,2) and increases to 2.5% in the hypertensive population undergoing angiography.(3) Incidence approaches 10% in autopsy series.(4) Despite increasing incidence, renal artery aneurysm rupture remains uncommon. We report the case of a man with chronic myelomonocytic leukemia who suffered bilateral renal artery aneurysm rupture over the course of 1 month.
