Liver abscesses caused by visceral larva migrans: Aimless wanderer separated from the host

Abstract

Visceral larva migrans (VLM) is a systemic zoonotic parasitic disease caused by migration of the second stage larva through viscera of humans. Despite being a foremost public health problem in low- and middle-income countries (LMICs) such as India, larva migrans remains an untended zoonosis. Here, we report two cases of VLM who presented with fever and abdominal pain for a prolonged duration. On further investigation, marked peripheral eosinophilia with multiple confluent necrotizing eosinophilic granulomas were identified on histopathological examination of the liver.

Keywords: Eosinophilia; granulomas; liver abscess; parasite; visceral larva migrans; zoonosis.
