ABSTRACT

Neuro-imaging studies (NI) in patients with complex partial seizures (CPC) demonstrate the epileptogenicity of a more or less localized underlying lesion. Correlation with the topography of the EEG focus permits affirmation of the origin. We analyze anomalies on NI and on the EEG of 151 patients with CPC. The EEG was abnormal in 128 and showed a unilateral epileptic focus in 117. NI was focal and unilateral in 72 of the 102 abnormal cases. Topographic correlation was 78.5%. This close correlation in our series makes us consider the localized lesions to be the probable aetiological factor.
