True renal artery aneurysms are rare. They are generally asymptomatic, however, a few may present with hypertension, rupture, or renal dysfunction secondary to distal embolization. Indications for intervention include aneurysm of ≥2.0 cm in diameter, renovascular hypertension, enlarging aneurysm, associated dissection /rupture, and aneurysms in women of child-bearing age/pregnancy. Endovascular therapy through coil embolization or stent graft exclusion is the recommended management. Coil embolization of the first and second order branch aneurysms is often associated with distal parenchymal loss and current stent graft technology prohibits use of these endoprostheses in the branch renal arteries. In this report, we describe successful stent-assisted coil embolization of an intraparenchymal aneurysm while preserving the distal parenchyma in a young woman with Neurofibromatosis type 1.
