Congenital complete absence of the pericardium mimicking myocardial infarction: a case report and literature review.

We present a case of a 56-year-old white male with a medical history of hypertension,who initially presented with chest pain, diaphoresis, and electrocardiogram (ECG) changes suggesting myocardial infarction. Initial frontal radiograph showed marked displacement of the cardiac silhouette into the left hemithorax. Cardiac catheterization was performed per hospital protocol showing no evidence of cardiac or coronary disease, but demonstrated marked rotation of the heart and abnormal displacement of the heart into the left hemithorax.

Chronic Pulmonary Embolism Mimicking Pulmonary Angiosarcoma.

We present the case of a 41-year-old woman who presented with chest pain. CT for possible pulmonary embolism showed a mass filling the left main pulmonary artery, with imaging features suggestive of pulmonary angiosarcoma. Open thoracotomy for excision of the mass revelaed no mass, only evidence of a chronic pulmonary thrombus of the left pulmonary artery.
