A cerebral laceration is a type of traumatic brain injury that occurs when the tissue of the brain is mechanically cut or torn. [1] 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. [2] [3] Lacerations require greater physical force to cause than contusions, [1] but the two types of injury are grouped together in the ICD-9 and ICD-10 classification systems.
A fifth of people with cerebral lacerations have a lucid interval and no significant changes in level of consciousness. [2] The level of consciousness decreases as the laceration bleeds and blood begins to build up within the skull. [2]
Cerebral lacerations usually accompany other brain injuries and are often found with skull fractures on both sides of the head. [2] Frequently occurring in the same areas as contusions, lacerations are particularly common in the inferior frontal lobes and the poles of the temporal lobes. [1] When associated with diffuse axonal injury, the corpus callosum and the brain stem are common locations for laceration. [1] Lacerations are very common in penetrating and perforating head trauma and frequently accompany skull fractures; however, they may also occur in the absence of skull fracture. [1] Lacerations, which may result when brain tissue is stretched, are associated with intraparenchymal bleeding ( bleeding into the brain tissue). [1]

A cerebral laceration with large amounts of blood apparent on a CT scan is an indicator of poor prognosis. [2] The progression and course of complications (health effects that result from but are distinct from the injury itself) do not appear to be affected by a cerebral laceration's location or a mass effect it causes.
