This paper reports a case of toxocariasis with cardiac manifestations. The patient was a 48-year-old man suffering from a Löffler endocarditis with hypereosinophilia. ELISA and Western blot tests confirmed the diagnosis of toxocariasis. The disease was successfully managed by a combination of albendazole and corticosteroids.
A few cases of cardiac toxocariasis have been described previously in the literature focusing on this unusual location. Eosinophils may have a key role in the pathogenesis of the disease. Therefore, clinicians should always investigate toxocariasis in case of hypereosinophilia with cardiac involvement.
