Clinical and laboratory observationsImprovement in Renal Cystic Disease of Tuberous Sclerosis Complex After Treatment with Mammalian Target of Rapamycin Inhibitor

Renal cysts occur in approximately 50% of patients with tuberous sclerosis complex, but their clinical significance and response to treatment are unknown. Abdominal imaging of 15 patients with tuberous sclerosis complex-associated renal cystic disease who had received mammalian target of rapamycin inhibitor therapy for other tuberous sclerosis complex-related indications was evaluated. Reductions in cyst number, sum diameter, and volume were observed.
