Cerebral laceration
Medical condition
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.
