VALDIVIA ALVAREZ, Ileana  e  ODALES IBARRA, Rogelio. Children with epilepsy of difficult control: Neuroimaging. Rev Cubana Pediatr [online]. 2009, vol.81, n.3. ISSN 0034-7531.

INTRODUCTION: Current studies of Neuroimaging are a great advance to etiologic and prognostic diagnosis of children epilepsy. The aim of present paper was to describe findings by axial tomography (AT) and magnetic resonance (MR) in children with epilepsy of difficult control, and to compare results of both techniques. METHODS: A descriptive, longitudinal and prospective study was made in 108 children diagnosed with epilepsy of difficult control, admitted in Neuropediatrics Service of "Juán Manual Márquez" Teaching Children Hospital from January, 2002 to June, 2006. The techniques used were: computed tomography (CT) and nuclear magnetic resonance (NMR). RESULTS: There were brain structural alterations in 88% of children and predominance of prenatal lesions in posterior fossa, migration disorders and atrophies secondary to perinatal hypoxia. They had a diagnosis of localized cortical atrophy by MR up to 28% of children. CONCLUSIONS: MR is the choice technique to study patients with epilepsy of difficult control due to its specificity, a great resolution, and relative harmless. Patients with located zones of epilepsy need brain functional studies to rule out focal cortical dysplasias.
