E
Venous bleeding is slow and subdural hematoma is common in older people.

The correct answer is E.
This history is fairly typical for subdural hematoma. Usually, the patient is elderly or alcoholic and has some degree of brain atrophy, causing the brain to pull slightly away from the skull. This stretches the bridging (penetrating) veins that cross the skull to connect to the cranial venous sinuses, leaving them very vulnerable to rupture after minor head trauma. This type of hematoma is due to venous, rather than arterial, hemorrhage and thus tends to develop rather slowly.
Epidural hematoma (choice A) is seen following severe head trauma causing laceration of the middle meningeal artery.
Mixed parenchymal and subarachnoid hemorrhage (choice B) can be seen with bleeding from AV malformations.
Multiple tiny hemorrhages of the putamen (choice C) are intraparenchymal hemorrhages associated with severe hypertension.
Subarachnoid hemorrhage (choice D) can be seen with bleeding from ruptured berry aneurysms.
