How a renal artery aneurysm may mimic renal stone?

Abstract

Renal artery aneurysm is a rare condition. Most patients are asymptomatic. This case presented to the emergency with colicky pain and underwent left transurethral lithotripsy for left ureteral stone, due to simultaneous renal stone candidates for percutaneous nephrolithotomy. In the review of the imaging, we found a large renal artery aneurysm, so vascular surgery consult was done and the patient managed with coil embolization Misdiagnosis of this condition could be led to life-threatening bleeding if percutaneous nephrolithotomy was done. It is recommended that renal artery aneurysm should be considered in the differential diagnosis of renal rim-like opaque lesions.
