TUMORS

OVERVIEW

Epileptogenic tumors are, in the majority, biologically benign lesions that do not usually change over time. As a result, they do not require oncological surgery and surveillance, instead their management centres on control of seizures. Some tumors are highly associated with refractory epilepsy, and are amenable to epilepsy surgery due to their anatomic and imaging features, epilepsy surgery is therefore an important treatment option for this group of patients.

The most common tumors associated with epilepsy are the glioneuronal tumors:

• dysembryoplastic neuroepithelial tumors (DNET); and
• gangliogliomas

Less commonly, epilepsy can be due to more aggressive tumors, these tumors require oncological surgery and surveillance, and are therefore not discussed in this section of EpilepsyDiagnosis.Org.
