RESUMEN
Cardiac tamponade, the accumulation of fluid in the pericardial space, leads to impaired venous return, loss of left ventricular preload, and hemodynamic collapse. The many causes of tamponade include malignancy, infection, inflammation, connective tissue disorders, and uremia. Herein, we report the case of a young woman who presented with syncope. She was found to have cardiac tamponade secondary to a chylous pericardial effusion that was due to a mature and benign anterior mediastinal cystic teratoma. Numerous reports have described pericardial effusions secondary to an anterior mediastinal cystic teratoma; however, to our knowledge, this is the 1st case of a teratoma causing chylopericardium that presented as tamponade.

Myocarditis is inflammation of cardiac muscle, which may be acute, subacute, or chronic with either focal or diffuse involvement of the myocardium. This leads to a cardiomyopathy with clinical features of heart failure as well as echocardiographic evidence of global dilation of the cardiac chambers. There are numerous reports in the literature of viral myocarditis causing dilated cardiomyopathy; however, there are no reports of recurrent viral myocarditis and vaccine-associated myocarditis in a single patient with complete reversal of the cardiomyopathy and return to normal cardiac function. We present a case of recurrent myocarditis in a female patient caused by a viral upper respiratory infection and streptococcal pneumonia vaccination who presented with recurrent episodes of reversible cardiomyopathy.
