Pediatric Renal Angiomyolipomas in Tuberous Sclerosis Complex.

Purpose: Tuberous sclerosis complex is a genetic disorder characterized by the growth of hamartomas in multiple organs. Up to 80% of patients with tuberous sclerosis complex will have at least 1 angiomyolipoma in their lifetime. We describe the incidence and natural history of angiomyolipoma in a pediatric tuberous sclerosis complex population and analyze tumor growth to determine optimal renal imaging intervals in an effort to improve counseling, treatment and followup.
