Abstract

Cardiac involvement in hypereosinophilia is rare; when present, it manifests as ventricular thickening, usually with fibrous tissue and mural thrombosis. We present a case of a 57-year-old man with an abnormal right ventricular apex with eosinophilia, which was caused by Toxocara canis infection.

Figure

  • Fig. 1 Electrocardiography demonstrated atrial flutter with a ventricular rate of 77 bpm (A). Chest radiograph showed cardiomegaly and blunting of the bilateral costophrenic angles (B).

  • Fig. 2 Transthoracic echocardiography showed an enlarged right atrium with spontaneous echo contrast without a definite thrombus and a normal left ventricular ejection fraction.

  • Fig. 3 There was a moderate pericardial effusion (A) and dense right ventricular apical trabeculations with a large hypoechogenic mass (arrow) occupying the apex (B).

  • Fig. 4 Right ventricular apical trabeculations with a hypoechogenic mass (arrow) occupying the apex existed 3 months prior at the outside hospital (A). A right atrial thrombus existed at that time (B), which disappeared after anticoagulation.

  • Fig. 5 After pericardiostomy, the pericardial effusion disappeared (A), and the dense right ventricular apical mass (arrow) was not altered (B).

  • Fig. 6 Chest computerized tomography showed a relatively hypodense, thickened right ventricular apical endomyocardium (A). Cardiac magnetic resonance imaging showed a thickened, hypodense right ventricular apex (white arrow, B) and hyperenhancement of the endomyocardial border (black arrow) was shown after administration of gadolinium (C).
