Treating subependymal giant cell astrocytoma in patients with tuberous sclerosis complex: an update of the literature.

Introduction: Subependymal giant cell astrocytomas (SEGAs) are one of the predominant features of the tuberous sclerosis complex (TSC). Before the use of mTOR inhibitors (mTORi; everolimus and sirolimus) in TSC, many patients had to undergo surgical operations (both preemptively and emergently). However, with mTORis gaining increased use, the role of medical and surgical therapy in SEGA is unclear.
