Resumo

O cisto aracnoide (CA) é formado pela divisão da membrana aracnoide contendo líquido cefalorraquidiano. Raramente, os pacientes apresentam sintomas neurológicos relacionados ao cisto. O caso apresentado é de um grande CA assintomático. Criança do sexo masculino apresentando na ressonância magnética do crânio grande CA, com efeito de massa no hemisfério direito e desvio da linha média. A criança encontrava-se assintomática com exame neurológico normal. A conduta foi conservadora. A decisão pelo tratamento cirúrgico ainda é motivo de debate. Mesmo na imagem descrita com um grande cisto aracnoide, continua sendo controverso o tipo de tratamento.

Abstract

 Arachnoid Cyst (AC) is formed by the division of the arachnoid membrane that contains cerebrospinal fluid. Rarely, patients have neurological symptoms related to the cyst. The case presented is of a large asymptomatic AC. A male child presented large AC on magnetic resonance imaging of the skull, with mass effect on the right hemisphere and midline shift. The child was asymptomatic with normal neurological examination. The chosen treatment was conservative. The decision for surgical treatment is still a matter of debate. Even in the image described with a large AC, the type of treatment remains controversial.
