Angiomyolipoma is a benign hamartoma. Seventy percent of angiomyolipomas occur sporadically in the general population and the remainder are associated with a syndrome. Of patients with tuberous sclerosis, 60 to 80% have an angiomyolipoma. Sporadic angiomyolipomas tend to be single and occur in an older age group. In tuberous sclerosis, the lesions are usually bilateral and multiple. Therapy is indicated when there are symptoms or when the lesion is greater than 4 cm. Criteria for further embolization include growth of the lesion by 2 cm at annual follow-up computed tomography and presentation with acute hemorrhage. We describe a case of a sporadic asymptomatic angiomyolipoma treated with absolute alcohol embolization.
