Abstract

Renal angiomyolipomas are uncommon benign tumors containing fatty tissue. Only a few cases of infiltrating angiomyolipomas have been reported. We aimed to describe a case of a 65-year-old woman presenting a peripheral angiomyolipoma of the left kidney with CT evidence of involvement of the renal vein. The lesion has been found incidentally during abdominal CT for an unrelated reason. The patient underwent surgical treatment considering the vascular extension of the lesion and the risk of thromboembolic complications. The pathological analysis confirmed the diagnosis of renal AML in the upper pole of the left kidney invading the renal vein without malignancy.No post-operative complications and the evolution was favorable.

Keywords: Angiomyolipoma; Computed tomography; Renal vein.
