This case is a nice example of a supine hemothorax on a trauma chest radiograph being identifiable as a generalized increase in hemithorax density compared to the contralateral side.  

CT Findings

  • Bilateral hemothorax, right greater than left
  • mild atelectasis adjacent to the hemothoraces
  • small pulmonary contusion and traumatic pneumatocele right lung base
  • multiple bilateral anterobasal incomplete rib fractures
  • right T10 transverse process and vertebral body fracture with adjacent locules of gas
  • trace bilateral pneumothorax anterobasally (very tiny!)
