Renal artery aneurysms: presentation of five cases.

We are presenting clinical characteristics, management and follow-up of five consecutive patients with renal artery aneurysm. Renal artery aneurysms are relatively uncommon, they rarely give rise to clinical manifestations and they are usually found incidentally. However with the introduction of Doppler ultrasound, computed tomography (CT) and magnetic resonance (MR) imaging, the diagnosis of renal artery aneurysms became more frequent.
