Where is a subdural hematoma located?

• A. Between dura and arachnoid membranes
• B. Between skull and dura
• C. Within brain tissue
• D. Between skull and brain

Answer: (A)

The location is in the space between the dura mater and the arachnoid mater. This “subdural space” is a potential space that becomes a real space when blood from torn bridging veins accumulates after head injury. Epidural hematomas sit between the skull and dura, intraparenchymal (inside brain tissue) bleeds occur within the brain tissue itself, and subarachnoid hemorrhages occur in the space between the arachnoid and pia, not between dura and arachnoid.
