The patient is a 68-year-old white female with mental retardation which is secondary tuberous sclerosis. During a work up for an elevated alkaline phosphatase, occult blood was discovered in her urine. An intravenous urogram demonstrated a large mass in the right kidney. A subsequent abdominal CT scan showed a 11 x 11 x 10 cm heterogeneous mass replacing the mid and lower portions of the right kidney with an area of central low density consistent with necrosis. The underlying kidneys exhibited numerous small low density foci.
