We relate a case of an 18-year-old man, resident of Xapuri (State of Acre, Brazil), with a history of repeated episodes of meningoencephalitis (three in one year), each one was examined by a local doctor. In our service (Emilio Ribas Institute of Infectology) we observed a patient with polyjoint aches, radiological and broncoscopical pulmonary alterations (without clinical features), meningeal and brain stem manifestations - with normal brain computed tomography and cerebrospinal fluid. Blood eosinophils and serological Toxocara canis test (ELISA) were greatly increased. With the hipothesis of Toxocariasis (Visceral Lana Migrans) we administered Thiabendazole that brought complete clinical and laboratorial remission. Lnspite of a new episode of headache with meningeal manifestation approximately one month later (treated with dexamethasone resulting in a full remission after three days) we have not finded other manifestations in approximately three and a half years of ambulatory' care.
