A tumor and cortical dysplasia may be the concomitant cause of the intractable
epilepsy, but a few studies have examined so far. From among 249 patients who
underwent surgery for intractable epilepsy at Dongsan Epilepsy Center, those in whom
neoplasia and cortical dysplasia coexisted were selected for this study, and were
reviewed the clinical, electrophysiological, neuro-imaging and pathological findings. In 17
of 25 lesion-related epilepsy patients, tumors including dysembryoplastic neuroepithelial
tumor(DNT)(n=6), ganglioglioma(n=5), gangliocytoma(n=1), low grade astrocytoma(n=2),
hypothalamic hamartoma(n=1) were verified. Of these 17 cases involving tumors,
concomitant cortical dysplasia was observed in 7 (DNT ; 6, ganglioglioma ; 1).
All these patients underwent sophisticated presurgical evaluation and intraoperative
acute recording(ECoG) for the identification of adjacent or remote epileptogenic areas as
well as functional brain mapping by electrical stimulating or SSEP to verify the eloquent
areas. In intractable epilepsy, the coexistence of cortical dysplasia and neoplasia is not
common, though careful intraoperative evaluation of the tumor and surrounding tissue
using electrocorticogram(ECoG) may lead to its pathological identification and excellent
surgical results for these rare lesions.
