Eosinophilic Myocarditis Associated with Visceral Larva Migrans Caused by Toxocara Canis Infection

A 41-year-old woman who was diagnosed with myocarditis presented eosinophilia. Since the antibody against Toxocara canis (T. canis) was positive, we diagnosed that she had visceral larva migrans due to T. canis associated with myocarditis. She was treated with oral albendazole and prednisolone for two weeks, eosinophil count and hepatic enzymes were normalized after completion of treatment. This is the first report of myocarditis caused by T. canis infection in Korea.

Eosinophillic myocarditis and coronary arteritis in a fatal case of asthma.

Mortality is very unusual in the case of asthma. We recently came across a fatal case of asthma which showed a rare combination of unusual complications like eosinophilic myocarditis, coronary arteritis, biventricular cardiac hypertrophy, eosinophilic pneumonitis and pulmonary hypertension.

A case of cardiac involvement in Churg-Strauss syndrome presenting without cardiomegaly in an asymptomatic patient / 대한내과학회지

We report a case of Churg-Strauss syndrome with cardiac involvement presenting without cardiomegaly or cardiopulmonary symptoms. A 47-year-old woman was referred to our institution for myalgia, peripheral numbness, and eosinophilia. She had been diagnosed with bronchial asthma and allergic rhinitis four years ago. The patient exhibited eosinophilia (71%) and elevated cardiac enzymes (cTnI, 2.977 ng/mL). Cardiomegaly was not observed on chest radiography, but nonspecific ST segment changes were observed on electrocardiography. A transthoracic echocardiography revealed a dilated left ventricular cavity, a decreased left ventricle (42%), and diastolic dysfunction. Contrast-enhanced cardiac magnetic resonance imaging revealed delayed hyperenhancement 10 minutes after injecting gadolinium. An endomyocardial biopsy showed eosinophilic myocarditis associated with vasculitis. The patient was diagnosed with Churg-Strauss syndrome and received combination therapy with steroid and cyclophosphamide. After the second treatment cycle, the blood eosinophilia disappeared and the vasculitis and infiltration of eosinophils into the endomyocardial tissue had completely resolved.

Eosinophilic Myocarditis Associated with Hypereosinophilia

A variety of disease states are marked by prolonged and profound eosinophilia associated with localized or widespread eosinophilic infiltrates. Cardiac involvement maybe a major cause of morbidity and mortality of this disease. We report a case of acute peri-myocarditis with eosinophilia, which was confirmed as eosinophilic myocardilic myocarditis by endomyocardial biopsy.
