title: Worsening right flank pain over a 24-hr period.
abstract: AML is a benign renal tumor composed of variable quantities of mature vascular, smooth muscle and fatty elements. They occur as an isolated finding, classically in middle-aged females, or in association with tuberous sclerosis. When symptomatic, they typically present with flank pain secondary to hemorrhage. CT is the diagnostic imaging modality of choice. The diagnosis can usually be made based on the recognition of fat within the lesion. When discovered, asymptomatic lesions are generally monitored by follow-up imaging studies, and if they remain stable, no intervention is required. Arterial embolization has become the recommended treatment of choice in some instances, particularly in cases with associated hemorrhage.
