Flail chest in a 46-year-old man. (2A) The surface-shaded display shows thoracic cage asymmetry caused by right-side rib 2–8 fractures at multiple sites causing flail chest (▴), and fractures of right-side ninth rib of posterior location. (2B) The axial CT scan shows a right-side hemothorax (★), pneumothorax (☆), and pulmonary parenchymal injuries, including contusion (write arrowhead) and laceration (write arrow), thoracic cage asymmetry caused by right-side rib fractures (black arrows), and a right scapular fracture (black arrowhead). Right-side subcutaneous air collection is also depicted. (2C) The coronal multi-planar reconstruction shows a right-side pneumothorax (☆), a pulmonary parenchymal laceration (write arrows) and a contusion, right-side rib fractures (black arrow), and right-side subcutaneous air collection (black arrowhead).
