RESUMO
Renal angiomyolipomas are uncommon benign neoplasms composed of mature fat tissue, thick-walled blood vessels and smooth muscle in varying proportions, which art often associated with tuberous sclerosis. During the last 5 years, 7 patients of renal angiomyolipoma were managed at Hanyang University Medical College. All cases were unilateral and were not associated with tuberous sclerosis. One patient was managed by radical nephrectomy because we could not distinguish from renal cell carcinoma. In 6 patients preoperative diagnosis were possible and one of them was managed by nephrectomy due to spontaneous rupture with severe bleeding and 5 patients were managed by conservative treatment. One patient was managed by enucleation of angiomyolipoma, and 2 patients were successfully managed with selective renal angioinfarct. Another 2 patients were incidentally found, small sized asymptomatic cases, so they were managed byobservation. All 7 patients were free of recurrence for follow up.
