Effective temporal lobectomy in childhood without invasive EEG

Abstract

Temporal lobectomy abolished complex partial seizures (CPSs) in 14 consecutive children (12 years or younger) whose presurgical evaluation included clinical analysis, scalp EEG, and neuroimaging. Seizures of 13 of 14 patients began with a simple partial component whose symptoms were suggestive of limbic system involvement. EEG recorded clinically typical seizures arising from the ultimately operated on temporal lobe in seven (50%) and never falsely lateralized seizure origin. Most active interictal spikes arose from the epileptogenic temporal lobe in 13 (93%) and never falsely lateralized epileptogenesis. Neuroimaging disclosed epileptogenic lesions in all: magnetic resonance imaging (MRI; 11 patients) and computed tomography (CT; three patients). Children may obtain relief from CPSs by temporal lobectomy without invasive electroencephalography.
