Abstracts

We describe an atypical clinical and electroencephalographic (EEG) pattern observed during the course of subacute sclerosing panencephalitis in a 14 year-old boy. In this patient with a two weeks history of partial complex seizures, the atypical EEG pattern was characterized by an initial left temporal focus which evolved to periodic lateralized epileptiform discharges (PLEDs) and, only during the 3rd and 4th weeks the typical bilateral and generalized periodic complexes appeared.

Descrevemos o quadro clínico e eletrencefalográfico atípicos observados durante a evolução de panencefalite esclerosante subaguda, em um menino de 14 anos. Neste paciente, com história de crises parciais complexas há duas semanas, o padrão eletrencefalográfico atípico foi caracterizado por foco temporal esquerdo que evoluiu para "periodic lateralized epileptiform discharges" (PLEDs), somente durante a 3ª e 4ª semanas surgindo os clássicos complexos periódicos difusos.

SUMMARY

We describe an atypical clinical and electroencephalographic (EEG) pattern observed during the course of subacute sclerosing panencephalitis in a 14 year-old boy. In this patient with a two weeks history of partial complex seizures, the atypical EEG pattern was characterized by an initial left temporal focus which evolved to periodic lateralized epileptiform discharges (PLEDs) and, only during the 3^rd and 4^th weeks the typical bilateral and generalized periodic complexes appeared.

Key words:subacute sclerosing panencephalitis, EEG, periodic complexes, partial complex seizure.
