Spontaneous rupture of a renal artery pseudoaneurysm in a previously hypertensive patient

Previously, renal artery pseudoaneurysms were thought to be extremely uncommon. However, these lesions are now being detected more frequently as incidental findings on computed tomography, magnetic resonance imaging, and the extensive use of angiography. The incidence of ruptured renal artery pseudoaneurysms is very low. We report a case of a giant renal artery pseudoaneurysm (9.4-cm diameter) with severe left flank pain and a syncopal attack in a young woman who did not control high blood pressure for a couple of years.
