Presentation
Incidental finding.
Patient Data
CT abdomen with contrast
At the bifurcation of the right artery, at an extra renal site, is a small saccular aneurysm (11 mm) , with no thrombus or intimal calcification.
The appearence of the renal arteries is otherwise normal.
Reduced caliber of the celiac trunk at the origin by the median arcuate ligament compression.
The right adrenal gland is extensively calcified.
Case Discussion
These aneurysms have a female predilection. Most are saccular and non-calcified and tend to occur at the bifurcation.
Most renal artery aneurysms (RAAs) are asymptomatic, but symptoms may develop from rupture, embolization of the peripheral vascular bed, or arterial thrombosis. RAAs are associated with hypertension.
A size greater than 2 cm is considered a thereshold for surgical treatment.
