Definition
By Mayo Clinic staffAn intracranial hematoma occurs when a blood vessel ruptures within your brain or between your skull and your brain. The collection of blood (hematoma) compresses your brain tissue.
An intracranial hematoma may occur because the fluid that surrounds your brain isn't able to absorb the force of a sudden blow or a quick stop. In these situations, your brain may slide forcefully against the inner wall of your skull and become bruised.
Although head injuries can be minor, an intracranial hematoma is a serious and potentially life-threatening condition that often requires immediate treatment.
Treating an intracranial hematoma often requires surgery to remove the blood. However, a smaller intracranial hematoma may not require surgery.
