A rare case of toxocariasis presenting with hypereosinophilic pericardial effusion and mycotic aneurysm.

Parasitic infections are the leading cause of hypereosinophilia in the paediatric population in tropical countries. We report an unusual case of infection in an eight-year-old boy who presented with intermittent fever, hypereosinophilia complicated by massive pericardial effusion and a mycotic aneurysm. This child received treatment with four weeks of albendazole and steroids.
