VALDIVIA ALVAREZ, Ileana; AGUILAR FABRE, Liane and FRANCISCO PEREZ, Alicia. Relation between electroencephalogram and neuroimaging present in children with epilepsy of difficult control. Rev Cubana Pediatr [online]. 2009, vol.81, n.3, pp. 0-0. ISSN 1561-3119.
INTRODUCTION: Focal epilepsies are the more frequent conditions in children and a pharmacologic treatment resistance could be present up to 30% of patients. Aim of present paper was to direct the attention to topographic coincidence of electroencephalographic paroxysms with structural lesions by neuroimaging facilitating the future therapeutical strategies design. METHODS: A descriptive, longitudinal, prospective study was conducted in 44 children diagnosed with epilepsy of difficult control admitted in Neuropediatrics Service of "Juán Manuel Márquez" Teaching Children Hospital from January, 2003 to June, 2007. At admission, we made electroencephalogram (EEG) and videoelectroencephalogram (VEEG) studies as well as neuroimaging studies by axial tomography (AT) or nuclear magnetic resonance (NMR). RESULTS: Paroxysms in EEG involved frontal lobule up to the 68% of patients. In 48%, electroencephalographic paroxysms coincide with structural alteration zones according neuroimaging, more frequent in frontal lobule. In 25% there is not topographic coincidence, and in 27% there are not specified structural alterations. CONCLUSIONS: In focal epilepsies of difficult control, we must to take care of eloquent zones with coincident between EEG and neuroimaging to assess in time the surgical treatment options.
