A subdural hematoma (American spelling) or subdural haematoma (British spelling), also known as a subdural haemorrhage (SDH), is a type of haematoma, a form of traumatic brain injury. Blood gathers within the outermost meningeal layer, between the dura mater, which adheres to the skull, and the arachnoid mater, which envelops the brain. Usually resulting from tears in bridging veins which cross the subdural space, subdural hemorrhages may cause an increase in intracranial pressure (ICP), which can cause compression of and damage to delicate brain tissue. Subdural hematomas are often life-threatening when acute. Chronic subdural hematomas, however, have better prognosis if properly managed.

In contrast, epidural hematomas are usually caused by tears in arteries, resulting in a build-up of blood between the dura mater and skull.
