Tuberous sclerosis with infantile spasm and subependymal giant cell astrocytoma

Tuberous sclerosis complex (TSC) is a genetic disease affecting many organ systems and showing different symptoms in each age group. We encountered a TSC patient with intractable epilepsy who had brain tumors suspected to be subependymal giant cell astrocytoma (SEGA). We used adrenocorticotropic hormone and ordinal antiepileptic drugs at first, but they showed limited effectiveness. After we tried several treatments for epilepsy, we started to use everolimus to prevent tumor growth. As a result, the development of the tumor stopped and the epileptic attack improved simultaneously. The frequency and duration of each epileptic spasm and seizure became milder, and the electroencephalogram findings also improved. The mental development had regressed when the epilepsy started, but it started to progress again after the epileptic attack disappeared. Everolimus may be used for treatment of intractable epilepsy with TSC in patients with a growing SEGA.
