Abstract

We performed a retrospective study of stereotactic resections of intra-axial brain mass lesions in 30 patients with intractable partial epilepsy. The most common pathologic alterations observed were vascular malformations (11 lesions) and glial neoplasms (11 lesions). The locations of the lesions included the postcentral gyrus in five patients, the precentral gyrus in five, and the deep-seated left posterior temporal region in four, all of which were sites that may have precluded standard craniotomy and cortical resection. Of the 30 medically refractory patients, 26 had at least an 80% reduction in seizure activity at a mean duration of follow-up of 22 months postoperatively. Nineteen of 22 patients with at least 1 year (mean, 28 months) of follow-up and 13 of 15 patients with at least 2 years (mean, 34 months) of follow-up had favorable surgical outcomes. “Lesionectomy” may allow pathologic examination of intracranial lesions and may produce a worthwhile reduction in seizure activity in some patients with intractable partial epilepsy.
