Abstract
Cardiac tamponade from ruptured intrathoracic organs can lead to sudden cardiac death. In rare circumstances, the pulmonary artery can be the source of hemopericardium. We describe a case of a 62-year-old woman with no significant past medical history, who presented with sudden unexpected death. A forensic autopsy revealed 500 ml of hemopericardium. Further dissection demonstrated a saccular aneurysm in the pulmonary artery trunk, along with the evidence of prior dissection, i.e., neointimal layer. Persistent ductus arteriosus (PDA) was also present. Pulmonary artery aneurysms (PAA) are rare and often associated with congenital heart disease (CHD). PDA is the most common CHD related to PAA. Secondary pulmonary hypertension makes the pulmonary artery vulnerable to medial degeneration and increases the risk of dissection and rupture. Careful inspection of the great vessels and congenital anomalies are essential in the forensic autopsies for sudden death investigation.
