Pulmonary lacerations. Axial MDCT in lung window at the level of pulmonary trunk. Multiple focus of pulmonary lacerations can be depicted, some of them are filled with air (pneumatocele, curved arrow), others filled with blood (hematocele-straight arrow), and some filled with both, making an air-liquid level (pneumo-hematocele, arrowhead). Surrounding pulmonary contusions are appreciated. Associated left pulmonary contusions and a small right pneumothorax are also depicted.
