title: Hepatic toxocariasis: a rare cause of right upper abdominal pain in the emergency department.
abstract: Toxocara canis and Toxocara cati are common helminths that reside in the intestinal tract of cats and dogs. Toxocariasis and, commonly, T. canis, is a disease commonly seen in children, which is characterised by hypereosinophilia, hepatomegaly, fever, transient pulmonary infiltration, and hypergammaglobulinaemia. Humans, who are not the actual host for these parasitic worms, are infected following oral intake of the infective eggs. Radiological differentiation of hepatic toxocariasis can be difficult, as liver lesions, which present as multiple hypoechoic lesions with regular borders, can look like a tumour, an infarction or an infection. We report on a case that presented to our emergency department (ED) with abdominal pain. During the initial review, the pathology in the liver was thought to be an infarction or an infection; however, the patient was diagnosed with hepatic toxocariasis following further evaluation.
