O bruxismo pode ser manifestação de epilepsia do lobo temporal? Relato de caso de uma criança com bruxismo e cisto hipocampal / Can bruxism be a sign of the temporal lobe epilepsy? Case reportof a child with bruxism and hippocampal cystic lesion

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 documentadopor 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.

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 childwith 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 betweenbruxism and epilepsy in this patient with potentially epileptogenic lesion is remote.

A Case of Isolated Choroidal Cystic Lesion With Good Visual Acuity

PURPOSE: To report a case of isolated choroidal cystic lesion in the macula with no interval change for two years. CASE SUMMARY: A 29-year-old woman who had suspicious maculopathy was referred to our clinic. Her best corrected visual acuity was 20/20 in the affected right eye, which showed a choroidal cystic lesion on a fundus exam, fluorescein angiography, USG and OCT. The multifocal ERG showed reduced amplitudes of the cystic area in the right eye, and SLO microperimetry revealed reduced retinal sensitivity in the cystic lesion as well as a stable fixation and spared foveal function. There was no evidence of underlying ocular disease in clinical assessment, and the lesion had not undergone interval change for the past two years.
