“…Experts recommend repair of an asymptomatic RAA if the diameter is 1.5 to 3 cm, although most suggest 2 cm. [5][6][7][8] However, it should be noted that rupture has been reported of aneurysms with diameters of 1.5 cm. Asymptomatic RAAs with a diameter of less than 2 cm should be followed by regular ultrasound or computed tomographic scan.…”

Renal artery aneurysms are uncommon, with an incidence of 0.01% in the general population. The improvement of radiologic techniques and the increased incidence of abdominal imaging for various indications has resulted in increased detection of asymptomatic renal artery aneurysms. Hilar renal artery aneurysms are a subtype of the disease and constitute management challenges. Here, we report 3 patients with hilar renal artery aneurysms treated with renal autotransplant and review the literature.

A 40-year-old woman was referred to our department for further investigation of a renal mass identified at an ultrasound (US) examination carried out in a private clinic because of abdominal pain. The mass was oval and hypoechoic, measured about 20 mm in diameter and was located near the left renal sinus; color Doppler showed peripheral blood flow. US examination carried out in our department using different equipment confirmed the presence of the mass but revealed intralesional blood flow suggesting aneurysm. This diagnosis was confirmed at subsequent computed tomography (CT) scanning and magnetic resonance imaging (MRI). The patient refused to undergo surgery and she is currently being monitored and has suffered no sequelae.Keywords Aneurysm Á Color Doppler Á Renal mass Á Ultrasound Riassunto Una donna di 40 anni giungeva alla nostra osservazione per la rivalutazione di una formazione renale identificata ad un esame ecografico effettuato esternamente per dolore addominale. Tale formazione, ovalare ipoecogena di circa 20 mm, era localizzata a livello del seno renale di sinistra e mostrava al color Doppler segnale vascolare perifericamente. Il controllo ecografico da noi eseguito con apparecchiatura più performante confermava la presenza della formazione evidenziando tuttavia segnale vascolare al suo interno e ponendo il sospetto di aneurisma, confermato poi ai successivi esami TC ed RM. La paziente rifiutava di sottoporsi ad intervento chirurgico terapeutico ed è tuttora in follow-up senza sequele.

A 52-year-old African-American woman with a history of Ehlers-Danlos type IV syndrome presented with chest and abdominal discomfort. A CT angiogram of the chest and abdomen was performed which revealed renal artery aneurysms. Panel A: the arrows point to the location of the renal artery aneurysms. (Image obtained using CT angiogram and post-processed using the volume rendering technique.) Panel B: the arrow points to a part of the right renal artery aneurysm that lacks contrast enhancement, which suggests thrombus formation. The arrowhead points to the left renal artery aneurysm that has contrast enhancement, which suggests flow. The ring enhancement around the renal artery aneurysms suggests calcium deposition. (Image obtained using CT angiogram.) Panel C: the thin arrow points to an area without contrast enhancement, which suggests thrombus formation. The arrowhead points to the aorta at the level of the renal arteries.The thick arrow points to an area of the aneurysm with contrast enhancement, which suggests flow. (Image obtained using CT angiogram and post-processed using the maximal-intensity-projection technique.) Owing to the spontaneous resolution of her symptoms and the complicated nature of Ehlers-Danlos type IV syndrome, she was treated conservatively with medications.Detection of renal artery aneurysms has increased due to the wide use of imaging modalities such as angiography, ultrasonography, computed tomography and magnetic resonance imaging. The estimated incidence ranges from 0.7% to 0.9% following angiography performed for renal and non-renal diseases. 1 The etiologies of renal artery aneurysm include atherosclerosis, fibromuscular disease and Ehlers-Danlos syndrome. 1 Renal artery aneurysm is slightly more common in women than men and affects the right renal artery more often. Bilateral renal artery aneurysms occur in 10-20% of positive studies. 1 Although the natural history of renal artery aneurysms is not known with certainty, potential complications include thrombosis, embolization, rupture and dissection. 1,2 Management options include observation, transcatheter occlusion or embolization, or surgical intervention. 1,2 Indications for intervention include an aneurysm diameter greater than 2.5 cm,
