Ruptured renal artery aneurysm: an uncommon cause of acute abdominal pain.
Previously thought to be extremely rare, renal artery aneurysms are now being found more commonly as incidental findings during the evaluation of refractory hypertension. Symptoms related to the aneurysm are uncommon and rupture occurs infrequently, but with devastating consequences. Factors predisposing to rupture include pregnancy, polyarteritis nodosa, and lack of aneurysmal calcification. Angiography is the study of choice for diagnosing the presence of visceral aneurysm and rupture. We report a case of ruptured renal artery aneurysm that presented with sudden onset of abdominal pain but no significant findings on physical examination. The patient's size precluded the detection of a pulsatile abdominal mass or the ability to obtain an abdominal angiogram. Computed tomography scan with contrast revealed the correct diagnosis, and successful treatment was initiated.
