Renal angiomyolipomas are uncommon benign neoplasms. From April 1990 to June 1993, 10 patients with angiomtyolipoma were followed clinically to determine the clinical course of angiomyolipoma. Average age of patient was 50 years (range 24 to 75)
and of
the patients 80% (range 2×1.5 to 13.8×9.1). Clinically the most common presenting complaint was abdominal/flandk pain and of the patients 40% were spontaneous reputre, 2 cases had hemorrhagic shock. The diagnosis and size was determined on the
basis
of ultrasonography/CT findings. Of 10 patients, 1 patient was observed, 3 patients were managed with nephrectomy and 6 patients were managed with emboliation. 10 patients were followed for an average 28 months (range of 12 to 50) by serial
radiological
imaging and clinical examination. The followup ultrasonography and/or CT scans were compared to the initial studies with respect to hemorrhagte, or change in size or composition of the tumor. One patient was managed with observation, symptoms
devloped
and tumor size increased 35 months later. 3 patients were free of disease for 20 to 50 months after nephrectomy. 5 of 6 patients managed with embolization, a radiological examination performed after the embolizaiton demonstrated the original mass
had
liquified and decrease in mass size. But 1 patient did not change in size and composition. These results demonstrate the selective embolization is an effective method as the primary therapy for control of hemorrhagic or symptomatic
angiomyolipomas
becausde of its parenchymal-sparing nature.
