Chest computed tomography scan at the level of the aortic arch demonstrating left-sided pneumothorax (horizontal black arrow) with high-density pleural effusion compatible with hemothorax. There is a large tear of the left pectoral muscles with distraction of the muscle tissue, and a large, air-filled, 5 cm- wide defect (vertical white arrow). Two chest tubes can be seen in the left hemithorax (horizontal white arrow). A large amount of subcutaneous emphysema tracking along the chest wall can also be appreciated.
