An intracranial hemorrhagic stroke occurs when a blood vessel in the brain ruptures. This lets blood spill into nearby brain tissue, which damages the cells. Other brain cells die because their normal blood supply is cut off. This type of stroke accounts for approximately 10 percent of all strokes.

Intracranial hemorrhage can result from physical trauma or from ruptured aneurysms or arteriovenous malformations (AVM).

Diagnosis
Neuroimaging technologies are used to diagnose intracranial hemorrhages such as: CT scans, Magnetic Resonance Imaging (MRI) and angiography.
