Polycystic kidney disease and chronic renal failure in tuberous sclerosis.

Tuberous sclerosis is a rare genetic disease which leads to formation of benign tumours in the brain and other organs of the body. It is a multisystem disease with various clinical manifestations. Renal angiomyolipomas are the most common renal manifestations whereas renal cell carcinoma is the least. Renal cysts are found in around 20% of the patients but polycystic kidney disease is present in less than 2% cases and is relatively rare manifestation of the disease. We present a case of tuberous sclerosis in a 60-year-old man who presented to the medicine outpatient department for routine evaluation of his hypertension. He was diagnosed as tuberous sclerosis. His ultrasound and CT scan of abdomen revealed polycystic kidney disease. His kidney function test and urine analysis were suggestive of chronic kidney disease.
