Abstract

Renal angiomyolipomas are uncommon benign neoplasms composed of mature adipose tissue, thick walled blood vessels and smooth muscle in varying proportions. Accurate preoperative diagnosis of renal angiomyolipoma is essential if conservative resection or angiographic embolization is to be used. In recent years, abdominal computerized tomography (CT) and renal ultrasonography have resolved the diagnostic dilemma, making detection of angiomyolipomas possible in almost all cases. Recently, we performed selective renal angioembolizations in 3 patients (2 females, 1 male). After followup period of 6 months to 1 year, all patient got better in clinical symptoms. In two of them the lesions decreased in size on followup CT but one patient showed suspicious malignant change and we performed the exploration to rule out renal malignancy. In our opinion, it is appropriate to perform the selective renal angioembolization for initial treatment of renal angiomyolipomas.
