Discussion (Related Text)

Renal artery aneurysms (RAA) are considered the second most common visceral aneurysm (15-22%), most common being splenic artery aneurysm (60%). They are more common in females. Most of the lesions are saccular and tend to occur at the bifurcation of main renal artery Most cases are asymptomatic. Symptoms usually arise from rupture of aneurysm, embolisation of peripheral vascular bed or arterial thrombosis 1. Hypertension is associated in up to 73% cases of these aneurysm. Haematuria has also been reported in many cases
Aetiology 1-2
•fibromuscular dysplasia (34%)
•degenerative aneurysm (25%)
•vasculitides (e.g. Behcet disease)
•phakomatoses (e.g. tuberous sclerosis, neurofibromatosis)
•intrinsic collagen deficiency (Marfan syndrome, Ehlers-Danlos syndrome)
Radiographic features
•noncontrast: soft tissue mass lesion in the region or course of renal artery
•postcontrast: contrast-filled outpouching in the course of the renal artery
Aneurysms can be well detected and characterized by angiography, in terms of size, neck diameter and type.
