Aortic intimal sarcoma masquerading as bilateral renal artery stenosis

Abstract

Aortic intimal sarcoma is a rare tumor with poor prognosis. The most common manifestations are thromboembolic phenomena and vascular obstruction. We present a case of aortic intimal sarcoma causing bilateral renal artery stenosis which manifested as resistant hypertension and acute kidney inury. Multiple attempts to stent the renal arteries were unsuccessful. Eventually the patient developed acute limb ischemia and oliguric kidney failure as complications of the primary tumor.
