Abstract

Spontaneous rupture of renal artery aneurysm is a rare, but life threatening complication with high mortality. The etiology of non-traumatic renal artery aneurysm is fibromuscular dysplasia, atherosclerosis, vasculitis, and pregnancy. We here report a case of spontaneous rupture of renal artery aneurysm in a patient with untreated hypertension. A 39-year-old non-pregnant woman complained of sudden onset of right flank and lower quadrant abdominal pain. Ultrasonography showed large fluid collection in right lower abdomen. Emergency laparotomy demonstrated huge retroperitoneal hematoma due to spontaneous rupture of right renal artery aneurysm. Microscopic examination of the aneurysmal wall revealed intimal hyperplasia without atherosclerotic change.
