RESUMO

OBJETIVO:

Alertar a comunidade pediátrica às consequências neurológicas da toxocaríase e descrever o primeiro caso pediátrico de neurotoxocaríase com acometimento simultâneo do cérebro, cerebelo e sistema nervoso periférico. DESCRIÇÃO Relatamos um caso de neurotoxocaríase em criança do sexo masculino, 5 anos de idade, previamente hígido, com sintomas incomuns e acometimento multifocal dos sistemas nervosos central e periférico. Discutimos o diagnóstico diferencial e fazemos uma breve revisão da literatura. Desde o início da década de 1950, menos de 50 casos de neurotoxocaríase foram descritos, a maioria em adultos.

COMENTÁRIOS:

A toxocaríase é uma das helmintíases mais comuns em humanos. A neurotoxocaríase, porém, é uma patologia rara, especialmente na população pediátrica. Embora a toxocaríase costume seguir um curso autolimitado, sem envolvimento do sistema nervoso central, as manifestações neurológicas podem ser devastadoras quando ocorrem. A neurotoxocaríase deve fazer parte do diagnóstico diferencial de pacientes pediátricos com sintomas neurológicos atípicos e eosinofilia no líquor. Se diagnosticada e tratada precocemente, é possível evitar as sequelas neurológicas a longo prazo.
ABSTRACT

OBJECTIVES:

To alert pediatricians to the neurologic consequences of toxocariasis and to describe the first pediatric case of neurotoxocariasis with concomitant cerebral, cerebellar and peripheral nervous system involvement. DESCRIPTIONS We report a case of neurotoxocariasis in a previously healthy 5-year-old boy with unusual symptoms and multi-site involvement of both the central and peripheral nervous system. Differential diagnoses are discussed and the relevant literature is reviewed. Since the early 1950s, fewer than fifty cases have been described, mostly in adult patients.

COMMENTS:

Although human toxocariasis is one of the most common zoonotic helminth infections, neurotoxocariasis is a rare condition, especially in pediatric patients. Although toxocariasis usually presents as a self-limiting disease with no central nervous system involvement, when it does occur, it can be devastating. Neurotoxocariasis should be added to the differential diagnosis of pediatric patients with unusual neurologic symptoms accompanied by high levels of eosinophils in the cerebrospinal fluid. Early diagnosis and treatment can prevent long-term neurologic sequelae.
