Renal Artery Aneurysm

Aneurysm of the renal artery is rare. It can occur as a manifestation of atherosclerotic disease, FMD, neurofibromatosis, and polyarteritis nodosa. Renal artery aneurysms can be classified as extra-parenchymal (saccular, fusiform, false/dissecting) or intraparenchymal. The incidence of hypertension in patients with renal artery aneurysms may reach 90%; however, this may reflect the importance of hypertension for ordering diagnostic an-giography. On 3D CE MRA, aneurysms involving the main and proximal segmental renal arteries are seen well (Fig. 11a, b). However, the smaller, in-traparenchymal aneurysms of polyarteritis no-dosa may not be reliably detected. Viewing reformations and source images is crucial for determining whether the aneurysm is saccular or fusiform. This may help to determine appropriate treatments for the patients, including surgery, tran-scatheter embolization, stent-graft or frequent follow-up imaging to assess for growth.
