    Pulmonary laceration

    A pulmonary laceration is a chest injury in which lung tissue is torn or cut. An injury that is potentially more serious than pulmonary contusion, pulmonary laceration involves disruption of the architecture of the lung, while pulmonary contusion does not. Pulmonary laceration is commonly caused by penetrating trauma but may also result from forces involved in blunt trauma such as shear stress. A cavity filled with blood, air, or both can form. The injury is diagnosed when collections of air or fluid are found on a CT scan of the chest. Surgery may be required to stitch the laceration, to drain blood, or even to remove injured parts of the lung. The injury commonly heals quickly with few problems if it is given proper treatment; however it may be associated with scarring of the lung or other complications.

  • Cerebral laceration

    A cerebral laceration is a type of traumatic brain injury that occurs when the tissue of the brain is mechanically cut or torn. The injury is similar to a cerebral contusion; however, according to their respective definitions, the pia -arachnoid membranes are torn over the site of injury in laceration and are not torn in contusion. Lacerations require greater physical force to cause than contusions, but the two types of injury are grouped together in the ICD-9 and ICD-10 classification systems.
