Intracranial hematomas are accumulations of blood within the brain or between the brain and the skull. An intracranial hematoma may occur because the fluid that surrounds your brain can't absorb the force of a sudden blow or a quick stop. The cause of intracranial bleeding (hemorrhage) usually is a head injury, often resulting from automobile, motorcycle or bicycle accidents, falls, assaults, and sports injuries.
Symptoms may include a persistent headache, drowsiness, confusion, memory changes, paralysis on the opposite side of the body, speech or language impairment, and other symptoms depending on which area of the brain is damaged. Some hematomas don't need to be removed because they're small and produce no signs or symptoms. But because signs and symptoms may appear or worsen days or weeks after the injury, if you don't have surgery, you may have to be watched for neurological changes, have your intracranial pressure monitored and undergo repeated head CT scans.
Blood-thinning medication, such as warfarin used but the treatment may need supportive therapy to reverse the effects of the medication and reduce the risk of further bleeding. Options for reversing blood thinners include administering vitamin K and fresh frozen plasma. Hematoma treatment often requires surgery.
During the 12-month study period, 366 patients with first-ever stroke were registered. A diagnosis of cerebral infarction or intracerebral hemorrhage was confirmed by computed tomography or autopsy in 42% of cases. The diagnosis of subarachnoid hemorrhage was established by cerebrospinal fluid examination in all 14 cases. The age- and sex-adjusted annual incidence rate for stroke was 232 per 100,000. The distribution of incidence cases by diagnostic category was as follows: cerebral infarction, 87.7%; intracerebral hemorrhage, 8.5%; and subarachnoid hemorrhage, 3.8%.
