Pharmacological treatment strategies for subependymal giant cell astrocytoma (SEGA).

mTOR inhibitors have largely replaced surgery as the primary modality for the management of SEGAs. Surgical treatment is largely limited to tumors that present with acute hydrocephalus and increased intracranial pressure. Patients with TSC should undergo periodic screening with CT or preferably MRI scans of the brain from childhood to approximately age 25 to identify SEGAs which require treatment. In addition to avoiding potential morbidity associated with surgical resection, mTOR inhibitors have the potential to improve the clinical status of tuberous sclerosis patients generally.
