Abstract

Sleep bruxism is a condition of high prevalence in childhood and has multifactorial causes. However, as a sign of temporal lobe epilepsy, it seems to be a rare event. There are reports of patients with bruxism related to temporal lobe seizures, showing that, exceptionally, an event such as teeth grinding may not be just a parasomnia. We present a child with bruxism, whose brain resonance shows cystic lesion compatible with choroid fissure cyst, which compresses the left hippocampus. Bruxism was documented by polysomnography, with extended electroencephalographic setup, without any electroencephalographic expression during episodes. Thus, we showed that the relation between bruxism and epilepsy in this patient with potentially epileptogenic lesion is remote.

Keywords

Bruxism, choroidal cyst, temporal lobe epilepsy, polysomnography.

Resumo

O bruxismo é uma condição multifatorial e de elevada prevalência na infância. Entretanto, como sinal de epilepsia do lobo temporal, parece ser um evento raro. Há registros de pacientes com bruxismo relacionado a crises do lobo temporal, demonstrando que, excepcionalmente, um evento como o ranger de dentes, pode não ser apenas uma parassonia. Apresentamos uma criança com bruxismo, cuja ressonância cerebral mostra lesão cística, compatível com cisto de fissura coróidea, que comprime o hipocampo esquerdo. O bruxismo foi documentado por polissonografia, com montagem eletrencefalográfica ampliada, sem qualquer expressão eletrográfica durante os episódios. Mostramos assim que a relação de bruxismo e epilepsia neste paciente com lesão potencialmente epileptogênica é remota.

Palavras-chave

Bruxismo, cisto de fissura coróidea, epilepsia do lobo temporal, polissonografia.
