Chest X Ray

Pulmonary laceration may not be visible using chest X-ray because an associated pulmonary contusion or hemorrhage may mask it.

Hematomas appear on chest radiographs as smooth masses that are round or ovoid in shape. Like lacerations, hematomas may initially be hidden on X-ray by lung contusions, but they become more apparent as the contusion begins to heal. Pneumatoceles have a similar shape to that of hematomas but have thin, smooth walls.[1] Lacerations filled with both blood and air display a distinctive "air-fluid level" on upright chest X-rays.[1]

Shown below is a chest X-ray of a right sided pulmonary contusion associated with flail chest and subcutaneous emphysema. Contusion may mask pulmonary laceration on chest X-ray.
