Bleeding into the space surrounding the brain is best described as Subarachnoid Hemorrhage.

• A. Subarachnoid Hemorrhage
• B. Intracerebral Hemorrhage
• C. Epidural Hematoma
• D. Subdural Hematoma

Answer: (A)

Understanding where bleeding occurs relative to the brain’s coverings clarifies this. The subarachnoid space is the area between the arachnoid membrane and the pia mater that surrounds the brain and contains cerebrospinal fluid. Blood in that space is a subarachnoid hemorrhage. This is different from bleeding within脑 tissue (intracerebral hemorrhage), which is inside the brain parenchyma; or bleeding between the skull and dura (epidural hematoma); or bleeding between the dura and arachnoid (subdural hematoma). So the description fits subarachnoid hemorrhage because the bleeding is in the space surrounding the brain.
