Subdural hematoma bleeds into which anatomical space?

Subdural hematoma bleeds into which anatomical space?

• A. In ventricles
• B. Between skull and dura
• C. Within brain parenchyma
• D. Between dura and arachnoid spaces

Answer: (D)

Subdural hematoma refers to bleeding into the space between the dura mater and the arachnoid mater. This subdural space is a potential space that becomes real when venous bridging veins tearing during trauma allow blood to accumulate there. It’s distinct from bleeding in the ventricles (intraventricular), within the brain tissue itself (intraparenchymal), or between the skull and dura (epidural). On imaging, subdural hematomas are typically crescent-shaped and can cross suture lines, reflecting their location between dura and arachnoid.
