Initial thoracic radiographs performed on presentation to the emergency department following hit by car thoracic trauma. Multiple pulmonary pneumatoceles (indicated by asterisks) and pneumothorax (arrows) appreciated with presence of pulmonary contusions and a mixed interstitial and alveolar pattern.

Thoracic radiographs (see Figure 1) revealed a diffuse mild to moderate interstitial lung pattern with ovoid gas lucencies (2.0-4.8 cm) superimposed over the right caudal lung lobes, moderate right-sided pneumothorax, and scant pleural effusion.
CT images revealing multiple pulmonary blebs (indicated by arrows), pulmonary pneumatocele formation (asterisks) and consolidating alveolar infiltrates within the right cranial and middle lung fields.

CT Scan (see Figure 2) identified multiple contused lungs, a consolidating alveolar infiltrate within the right cranial, middle, and right and left caudal lung lobes, pulmonary blebs and traumatic pulmonary bulla with the largest structure measuring ~6.6 x 3.3 x 3.2 cm and the presence of dependent fluid accumulation consistent with pulmonary hemorrhage.
Repeat ventrodorsal thoracic radiographs following thoracostomy tube removal. There is marked improvement in pulmonary contusions with persistence of a heavy coalescing mixed interstitial and alveolar pattern persisting diffusely in the right hemithorax. Pneumothorax (arrows) also persistent.

Repeat ventrodorsal thoracic radiographs revealed marked improvement in pulmonary contusions with a heavy coalescing mixed interstitial and alveolar pattern persisting diffusely in the right hemithorax (see Figure 3).
