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.
Early recognition of this injury is crucial for survival. Infants who have experienced a difficult operative delivery or are suspected to have a SGH require ongoing monitoring including frequent vital signs (minimally every hour), and serial measurements of hematocrits and their occipital frontal circumference, which increases 1 cm with each 40 mL of blood deposited into the subgaleal space.
This is a shortened version of the seventeenth chapter of the ICD-9: Diseases of the Digestive System.It covers ICD codes 800 to 999.The full chapter can be found on pages 473 to 546 of Volume 1, which contains all (sub)categories of the ICD-9.
Cerebral contusion (Latin: contusio cerebri), a form of traumatic brain injury, is a bruise of the brain tissue. [2] Like bruises in other tissues, cerebral contusion can be associated with multiple microhemorrhages, small blood vessel leaks into brain tissue. Contusion occurs in 20–30% of severe head injuries.

Clinical manifestations of intraparenchymal hemorrhage are determined by the size and location of hemorrhage, but may include the following: [citation needed] Hypertension, fever, or cardiac arrhythmias
Subarachnoid hemorrhage may also occur in people who have had a head injury. Symptoms may include headache, decreased level of consciousness and hemiparesis (weakness of one side of the body). SAH is a frequent occurrence in traumatic brain injury and carries a poor prognosis if it is associated with deterioration in the level of consciousness ...
A head injury is any injury that results in trauma to the skull or brain. The terms traumatic brain injury and head injury are often used interchangeably in the medical literature. [ 1 ] Because head injuries cover such a broad scope of injuries, there are many causes—including accidents, falls, physical assault, or traffic accidents—that ...
Chronic subdural bleeds develop over a period of days to weeks, often after minor head trauma, though a cause is not identifiable in 50% of patients. [11] They may not be discovered until they present clinically months or years after a head injury. [25] The bleeding from a chronic hematoma is slow and usually stops by itself.
