Normal chest

Subcutaneous emphysema: Soft tissue injury / fracture

Subcutaneous emphysema: could be from rib fracture, stab wound, larynx or tracheal injury

Blunt chest injury with fracture ribs, subcutaneous and mediastinal emphsyema, extend down to abdominal wall and retroperitoneum

Lung contusion: Seen as patchy / alveolar density

Unilateral lung contusion, DDx aspirated pneumonia

Pulmonary contusion, DDx pneumonia

Lung contusion

Air bronchograms:

Resulted from:Alveolar pathology eighter fluid (exudate, edema blood) or cell (alveolar cell ca) or alveolar atelectasis (surfactant def.)

Pulmonary contusion

Pulmonary edema / ARDS as a consequence of lung contusion with subpneumonic gas

What is your diagnosis?

Tension pneumothorax

Tension pneumothorax

RLL atelectasis, AP: right retrocardiac density

Lat: Ligh vertebral sign

RUL Atelectasis

Mediastinal emphysema: could be from rib fracture, trachea injury, esophageal injury

Pneumo-mediastinum:

Better seen in lateral view as lucent streak outline great vessel and heart

Rib fractures, subcutaneous emphsyema, mediastinal emphysema, pneumopericardium and lung contusion.

Pneumomediastinum and lung contusion: angle wing sign
