Low-grade epilepsy-associated tumors in pediatric patients: A focused review of the tumor differential and current treatment options

Abstract

Seizures associated with low-grade tumors in pediatric patients can be drug resistant and associated with significant morbidity. There are several low-grade tumor types associated with epilepsy in this population with the majority localized to the temporal lobe and some extra-temporal locations (frontal, parietal, and occipital lobes). The primary treatment of low-grade epilepsy-associated tumors is surgical resection, though the surgical approach and the use of intraoperative techniques remain controversial. Newer treatments are under investigation as primary and/or adjunctive therapy, including non-invasive surgical options and gene-targeted therapy. A multimodal approach to treatment may improve long-term outcomes and quality of life.
