Pulmonary toxocariasis: a case report and literature review.

ABSTRACT

Toxocariasis is a parasitic disease caused by Toxocara canis or T. cati. We report a patient with toxocariasis who presented with dyspnea, high-grade eosinophilia, and bilateral pulmonary nodules. To further characterize the pulmonary manifestations of toxocariasis, we have reviewed 11 previously published pulmonary toxocariasis cases. The most common pulmonary symptoms in our review were cough and dyspnea, and the most common finding on chest imaging was bilateral pulmonary nodules. Risk factors for Toxocara infection primarily included exposure to dogs. Most patients received albendazole and responded well. A high index of suspicion is needed to diagnose this otherwise preventable parasitic disease.
