Visceral toxocariasis from regular consumption of raw cow liver.

A 58-year-old man had leukocytosis (leukocytes 11,800/ μL), with marked eosinophilia (36%) and an increased total IgE at 2,345 U/mL (normal <100). There were no abnormal results in his annual check-up examinations including blood parameters until the most recent examination, when he began to eat raw cow liver weekly. Abdominal computed tomography (CT) revealed multiple, ill-defined, low-attenuated lesions in the patient’s liver (Picture 1). Chest X-ray images did not reveal apparent abnormalities, whereas chest CT demonstrated a nodule with a halo and ill-defined margin, and ground-glass opacity (Picture 2). Gel diffusion test using the patient’s serum revealed strong precipitin bands
