Blunt coronary injury presenting as massive left-sided hemothorax.

Hemothorax after blunt trauma results from injury to intrathoracic structures or the chest wall. Tube thoracostomy is the most common mode of treatment; depending on the type of injury, it is frequently the only intervention required. Rarely, blunt cardiac injury can produce hemothorax if a communication exists between the pericardium and pleural space. We describe such a case that highlights the importance of a broad differential diagnosis when treating acutely injured patients.
