Human toxocariasis is an important parasitic zoonosis caused by larval forms of toxocara, a nematode parasite of dogs and cats. The migration of the larva through the different soft tissues in humans generates a series of clinical entities, such as: covert toxocariasis, visceral larva migrans syndrome, ocular toxocariasis and neurotoxocariasis. The clinical case of a six-year-old patient is presented, hospitalized as a result of an acute febrile syndrome associated with abdominal pain; whose physical examination revealed meningeal signs, photophobia, fundus alterations and moderate eosinophilia. Taking into account the epidemiology, the clinical picture and the results of serological studies, the diagnosis of ocular larva migrans was concluded, for which specific treatment was used with a satisfactory evolution. This nosological entity requires an adequate socio-epidemiological assessment of the patients, as well as a thorough physical examination that, together with the specific tests, will allow early diagnosis and timely treatment.

Keywords : Larva migrans; larva migrans, visceral; toxocariasis; zoonoses.
