COEXISTING RENAL ARTERY ANEURYSM AND SPLENIC ARTERY ANEURYSM IN A MIDDLE-AGED WOMAN

Abstract

The patient, a 51-year-old woman presented with microhaematuria for fi ve years. She had called at the local medical clinics and renal cyst lesion or angiomyolipoma were suspected. Later, she had follow-up at our hospital and microhaematuria was still noted. The abdominal plan fi lm showed ring-like calcifi cation near the kidney shadow. Subsequently, the abdominal sonography showed highly suspicious left renal artery aneurysmal dilatation. The following computed tomography scan of abdomen (Figure 1, 2) disclosed coexisting left renal artery aneurysm (measured 2.5×1.3×3.0 cm in size) and distal splenic artery aneurysm (measured 1.0×0.7×1.0 cm in size). Considering the persistent and aggravating clinical symptoms, surgical intervention was indicated. In general, about 50% of renal arterial aneurysm demonstrated ring-like calcifi cation in or near the renal hilum on a plain abdominal radiograph. The majority of renal arterial aneurysms are small and asymptomatic. The most common clinical manifestations are hypertension, subcostal or fl ank pain, haematuria, abdominal bruit, and, rarely, a palpable pulsating mass. Complications of renal arterial aneurysms include peripheral dissection, arterial thrombosis with renal infarction,
