Abstract

Human toxocariasis is a parasitic disease caused by Toxocara canis or Toxocara cati. We report a patient with toxocariasis who presented with dyspnea and left pleural effusion. All patients with toxocariasis in published case reports had serum eosinophilia. This is the first case report of eosinophilic pleural effusion without serum eosinophilia caused by toxocariasis infection, which was confirmed by using enzyme-linked immunosorbent assay (ELISA). Therefore, an antibody ELISA can be useful for diagnosing toxocariasis in patients with a pleural effusion of unknown cause, even in the absence of serum eosinophilia.
