Tuberous sclerosis and polycystic kidney disease. A case report

The patient was a 27-year-old man, complaining of generalized seizure and progressive abdominal distension. His clinical features were chracterized by epilepsy, mental retardation, skin abnormalities including adenoma sebaceum, shagreen patch and ash-leaf spots. Abdominal computed tomography demonstrated numerous variable sized cysts throughout both kidneys. Clinical and laboratory findings revealed chronic renal failure due to severe polycystic kidneys. On reviewing the literature, the present case is the first report of polycystic kidneys associated with tuberous sclerosis in Korea.
