Wear a helmet and make sure your kids wear helmets.A head trauma can result in multiple severe intracerebral hematomas. Diseases can cause spontaneous leakage of blood into the brain. There are many causes, including trauma, rupture of a bulging blood vessel (aneurysm), poorly connected arteries and veins from birth, high blood pressure, and tumors. This type of hematoma, also known as intraparenchymal hematoma, occurs when blood pools in the tissues of the brain. Intracerebral (intraparenchymal) hematoma An epidural hematoma that affects an artery in your brain can be deadly without prompt treatment. Some people with this type of injury remain conscious, but most become drowsy or go into a coma from the moment of trauma. The most common cause of an epidural hematoma is trauma. Blood then leaks between the dura mater and the skull to form a mass that presses on brain tissue. Take aspirin or other blood-thinning medication dailyĪlso called an extradural hematoma, this type occurs when a blood vessel bursts between the outer surface of the dura mater and the skull.The risk of subdural hematoma increases as you age. For example, bumping your head while getting into the car can cause bleeding, especially if you're on blood-thinning medication.Īll three types require medical attention as soon as signs and symptoms appear so that permanent brain damage can be prevented. You might not remember hurting your head. The result of less severe head injuries, this type of hematoma can cause slow bleeding, and symptoms can take weeks and even months to appear. Signs and symptoms take time to develop, sometimes days or weeks after the injury. This most dangerous type is generally caused by a severe head injury, and signs and symptoms usually appear immediately. The three types of subdural hematomas are: A hematoma that gets bigger can cause gradual loss of consciousness and possibly death. The leaking blood forms a hematoma that presses on the brain tissue. This occurs when blood vessels burst between your brain and the outermost of three protective layers that cover your brain (dura mater). There are three categories of hematoma - subdural hematoma, epidural hematoma and intracerebral (intraparenchymal) hematoma. You can have a serious injury even if there's no open wound, bruise or other obvious damage. This is especially true if you're taking a blood-thinning medication or an anti-platelet drug, such as aspirin. If you're an older adult, even mild head trauma can cause a hematoma. A head injury may result from motor vehicle or bicycle accidents, falls, assaults, and sports injuries. Request an Appointment at Mayo Clinic CausesĪ head injury is the most common cause of bleeding within the skull.

You might develop signs and symptoms of an intracranial hematoma right after a head injury, or they may take weeks or longer to appear.
