An Uncommon Cause of Pulmonary Embolism Leading to a Cardiac Arrest

An Uncommon Cause of Pulmonary Embolism Leading to a Cardiac Arrest

Compression of pulmonary arteries caused by mediastinal lymphadenopathy is an uncommon cause of pulmonary embolism: it is important that it is diagnosed correctly because its treatment and prognosis are different from that of pulmonary embolisms. Herein, we report the case of a young man with unknown mediastinal sarcoidosis and massive lymphadenopathy, which caused external compression of the pulmonary artery and led to rapidly fatal acute heart failure secondary to a massive pulmonary embolism.
