Intraventricular hemorrhage has been found to occur in 35% of moderate to severe traumatic brain injuries. [12] Thus the hemorrhage usually does not occur without extensive associated damage, and so the outcome is rarely good. [13] [14]
Epidural hemorrhage (extradural hemorrhage, EDH) which occur between the dura mater (the outermost meningeal layer) and the skull, is caused by trauma. It does not cross the suture lines of the skull because the superifical dural layer is attached tightly to the skull along the suture lines.
Intraventricular hemorrhage has been found to occur in 35% of moderate to severe traumatic brain injuries. [3] Thus the hemorrhage usually does not occur without extensive associated damage, and so the outcome is rarely good. [4] [5]
Cerebral amyloid angiopathy may cause intraparenchymal hemorrhage even in patients without elevated blood pressure. Unlike hypertension, cerebral amyloid angiopathy does not typically affect blood vessels to deep brain structures. Instead, it is most commonly associated with hemorrhage of small vessels in the cerebral cortex. [2]
Epidural hematoma involves bleeding into the area between the skull and the dura mater, the outermost of the three membranes surrounding the brain. [11] In subdural hematoma, bleeding occurs between the dura and the arachnoid mater. [23] Subarachnoid hemorrhage involves bleeding into the space between the arachnoid membrane and the pia mater.

A brain bleed, or hemorrhagic stroke, can occur for a variety of reasons and can be deadly. ... Nearly 45% of patients with a "spontaneous intracerebral hemorrhage," or brain bleeding, do not ...
A 22-year-old college student had to be put on life support after suffering a brain hemorrhage during a spring break trip to Mexico.
The interior of the skull has sharp ridges by which a moving brain can be injured. The most common cause of intracranial epidural hematoma is head injury, although spontaneous hemorrhages have been known to occur. Epidural hematomas occur in about 10% of traumatic brain injuries, mostly due to car accidents, assaults, or falls. [3]
