Ultrasonography and US guided liver biopsy techniques were successfully used to evaluate hepatic lesions of visceral larva migrans by Toxocara canis infection. A 63-year-old man who had a history of eating raw chicken, wild boar and horse meat was admitted because of leukocytosis and eosinophilia. He had no symptoms. However, abdominal ultrasonography revealed multiple small hypoechoic nodular lesions with unclear margin in the liver. US-guided target biopsy proved the lesions to be eosinophilic granuloma. The diagnosis of Toxocara canis infection was made by serological studies. Other imaging studies, including MRI, were also shown.
