RESUMO

Paroxismos occipitais aparecendo com o fechamento dos olhos (POFO) constituem o padrão eletrencefalográfico fundamental da epilepsia idiopática da infância com paroxismos occipitais (EIIPO). A associação de POFO e epilepsia idiopática tem sido questionada. Estudamos 24 pacientes que apresentavam POFO. A idade esteve compreendida entre 3 e 25 anos. Em 12 casos havia atividade epileptiforme de outras localizações (generalizada em 8 e rolândica em 4). Em 4 casos havia desorganização da atividade de base. Crises epilépticas espontâneas foram relatadas em 16 pacientes sendo focais em 9, generalizadas em 6 e inclassificáveis em um caso. Foi possível identificar as seguintes síndromes epilépticas: EIIPO em 7 casos; epilepsia benigna com pontas centro-temporais em um; EIIPO ou epilepsia benigna com pontas centro-temporais em um; epilepsia parcial sintomática/criptogênica em 4; idiopática generalizada em 2 e convulsões febris em 2 pacientes. Assim, concluímos que POFO foram mais comumente associados às epilepsias benignas da infância mas ocorreram em várias síndromes epilépticas ou mesmo em pacientes sem manifestações convulsivas.

SUMMARY

Paroxysms of high-amplitude spike-waves or sharp waves recurring rhythmically on the occipital areas when the eyes are closed (POEC) are primarily observed in childhood epilepsy with occipital paroxysms (CEOP). An association of this electroencephalographic (EEG) pattern with idiopathic epilepsy has been disputed. We studied EEG and clinical features in 24 patients (age ranging from 3 to 25 years) with POEC. The EEG showed generalized discharges in 8 cases, rolandic spikes in 4 and background abnormalities in 4 cases. Eigtheen (75%) patients manifested epileptic seizures. The nonfebrile seizures (16 cases) were partial (9 cases), generalized (6 cases) and unclassified (one patient). Two children had neurological examination or computed tomography abnormalities. Clinical and EEG data allowed for the following epileptic syndromes diagnosis: CEOP, 7 cases; benign childhood epilepsy with centrotemporal spikes, one case; CEOP or benign childhood epilepsy with centrotemporal spikes, one case; partial symptomatic/cryptogenic epilepsy, 4 cases; generalized idiopathic, 2 cases; febrile convulsions, 2 cases. We conclude that POEC may be observed in cases with different types of idiopathic partial, cryptogenic/symptomatic and idiopathic generalized epilepsies and may also occur in patients with no seizures.

Key words: focal epilepsy, electroencephalography, childhood.
