Subdural hematoma occurs in which space?

Subdural hematoma occurs in which space?

• A. Under the dura mater
• B. Between the skull and dura mater
• C. In the subarachnoid space
• D. Within the ventricles

Answer: (A)

Subdural hematoma forms in the subdural space, the space between the dura mater and the arachnoid mater. It typically results from tearing of bridging veins that traverse this area, allowing blood to accumulate there. This space is distinct from the epidural space, which lies between the skull and dura; from the subarachnoid space, which lies between the arachnoid and pia and contains cerebrospinal fluid and vessels; and from the ventricles, which are internal cavities within the brain where intraventricular bleeding would occur. So the correct location for a subdural hematoma is the subdural space.
