ABSTRACT
A 30-year-old man, who had kept a dog for nine years and often ate raw beef liver, visited a hospital because of a chest nodular shadow in the left lung field found on a checkup examination. Chest computed tomography obtained 8 days after the checkup showed no abnormal shadow in the left lung but two nodular shadows with halos in the right upper and lower lobes. Peripheral blood eosinophil counts and serum IgE values were elevated. Immunological examination including microplate ELISA showed a high titer of specific antibody against Toxocara canis in the serum. He was successfully treated with albentazole. Parasitic disease, especially toxocariasis, is an important consideration in the differential diagnosis of migratory nodular shadow with a halo on chest computed tomography, and serology is useful in diagnosis screening.
