A fifty-four-year-old woman without the clinical features of tuberous sclerosis underwent nephrectomy at age thirty-three years for angiomyolipoma, and twenty-one years later severe renal failure developed. At necropsy the remaining kidney had extensive angiomyolipomatous involvement; not until the brain was examined was the diagnosis of tuberous sclerosis made. To date, this would appear to be the third case without clinical tuberous sclerosis in which renal involvement was the sole clinical expression of tuberous sclerosis, and the seventh reported instance of renal failure due to renal angiomyolipomatous hamartomatous transformation.
