A Case of Renal Artery Aneurysm with Calcification / 대한비뇨기과학회지

ABSTRACT

Renal artery aneurysms, previously considered to be rare, have been diagnosed more frequently in recent years mainly due to extensive use of angiography. Most aneurysms are asymptomatic, found incidentally, and their presenting symptoms may include microscopic or gross hematuria, flank pain and renovascular hypertension. The diagnosis may be highly suggestive when rim like calcification is exist on KUB with symptoms, and renal angiography is needed to confirm diagnosis. The treatment may be conservative or operative according to size and site. Operative management may include nephrectomy, revascularization, and aneurysmectomy. We report a case of left renal artery aneurysm with incomplete ring-like calcification in a 52-year-old hypertensive woman. The selective renal angiography showed renal artery aneurysm arising from the bifurcation of left main renal artery Because of the risk of aneurysmal rupture through its weak portion with incomplete calcification and the possibility of the renovascular hypertension due to anastomotic stenosis after aneurysmectomy, we performed nephrectomy.
