One of the rare patterns of renal involvement by tuberous sclerosis is oncocytoma. This is a report of a known male patient diagnosed with tuberous sclerosis. He was asymptomatic, but his periodic abdominal ultrasound examination revealed bilateral renal masses. CT and MRI confirmed the presence of these masses which were proven histopathologically to be multiple oncocytomas.
