Toxocariasis is the infection of the human host with either Toxocara canis or Toxocara catis . Their definitive hosts are the domestic dog and cat, in which they live as adults within the lumen of the small intestine.1 Humans become infected after ingesting embryonated eggs from soil (geophagia, pica) or after exposure to dirty hands, raw vegetables, or larvae from undercooked giblets.2 The dominant clinical manifestations associated with toxocariasis are classified according to the organs affected. There are two main syndromes: visceral larvae migrans (VLM), which encompasses diseases associated with the major organs; and ocular larva migrans, in which pathologic effects on the host are restricted to the eye and the optic nerve.1,3–5 Clinical involvement of the CNS due to Toxocara species is rare and probably occurs as a result of hematogenous dissemination.4 This report describes a 2-year-old girl presenting neurotoxocariasis and an MRI pattern similar to acute disseminated encephalomyelitis (ADEM). A 2-year-old girl presented monthly episodes of fever and cough for approximately 1 year. Treatment during these episodes …
