“…Associations of renal artery aneurysms include fibromuscular dysplasia [3,13,14], neurofibromatosis [15], renal transplants [16][17][18], arterial dissection and infective and inflammatory arterial conditions [19,20]. There are rare reports in childhood [21]. In our study, blunt trauma, fibromuscular dysplasia and post-bypass vein grafting accounted for one case each; the etiology was presumed secondary to atherosclerosis in five cases and idiopathic in one.…”

The use of contrast-enhanced magnetic resonance angiography (CE-MRA) in screening for suspected renovascular disease may result in increased detection of renal artery aneurysms. We report the CE-MRA findings at diagnosis and follow-up in nine hypertensive patients with unsuspected renal artery aneurysms. A search of renal CE-MRAs of suspected renal artery stenosis at two tertiary referral institutions over 5 1/2 years was performed. All patients underwent CE-MRA using a fast spoiled gradient echo technique (TR/TE/flip 5.1-6 ms/1.6 ms/40 degrees), scan matrix 512 x 196-224, 1 excitation, FOV 400-450 mm x 266-360 mm, 32-50 mm x 1.5-2 mm interpolated slices. Gadolinium-enhanced 3D images were obtained during breath holding. Images were evaluated and post-processed on a workstation by a single operator. Nine patients with renal artery aneurysms out of a total of 912 cases were found, all involving the main artery or divisions proximal to the renal hilum. Renal arteries distal to the hilum were not consistently visualized. The aneurysm was bilobed in one patient, multilocular in another and unilocular in all others. Severe stenosis of the renal artery proximal to the aneurysm was present in two. Four patients underwent follow-up showing no change in aneurysm size. CE-MRA reliably identifies aneurysms involving the main renal arteries and proximal branches. Once diagnosed, CE-MRA offers a safe, non-invasive modality for surveillance of aneurysm if active intervention is not planned.

“…Renal Doppler ultrasonography is a good non-invasive method for evaluation of renal size and flow, but angiography remains the goldstandard for diagnosing aneurysms within the renal arterial system 8. Fortunately, rupture is unusual during childhood, but it represents a serious threat in adult life 1…”

Renovascular hypertension in an 8-year-old girl

et al. 2013

SUMMARYSecondary hypertension is the most common form of hypertension in childhood, particularly in the young age group: parenchymal disease and lesions of the renal artery account for the majority of such cases. Renal artery aneurysms (RAA) are rare and are usually diagnosed by Doppler ultrasonography or angiography performed in the investigation of specific clinical symptoms. We report herein a case of severe arterial hypertension in an 8-year-old girl arising from a large saccular RAA. Intravenous antihypertensive drugs were necessary to achieve blood pressure control and the final diagnosis was obtained from angio-CT scan and selective angiography that demonstrated a large saccular aneurysm of the left renal artery with parietal calcification. After confirmation of inexistent function of the entire left kidney by Tc99m-MAG3 renal isotope scan, nephrectomy was performed. The child's blood pressure further normalised and, 1 month after surgery, she had ceased any antihypertensive therapy. BACKGROUND

“…Nevertheless, CDS may be useful in the evaluation of renal vascular pathology. [2][3][4] RAA localization could be extraparenchymal or intraparenchymal. The former type comprises approximately 85% of all RAAs and is divided into saccular (70%), fusiform (20%), and dissecting (10%) aneurysm; the other 15% of RAAs are the latter type.…”
