A subdural hematoma occurs when a blood vessel near the surface of the brain bursts. Blood builds up between the brain and the brain's tough outer lining. The condition is also called a subdural hemorrhage. In a subdural hematoma, blood collects immediately beneath the dura mater. The dura mater is the outermost layer of the meninges.
Small ones are in the form of bruises, and greater swellings emerge with sprained joints and partially or completely ruptured muscles. Hematoma is formed when, during a blow or sprain, one or more blood vessels break and blood goes into the sub dermal area, into the joint itself, or between the muscles.
