Which term is defined as collection of blood within the subdural space?

• A. Subarachnoid hemorrhage
• B. Parkinson's Disease
• C. Subdural hematoma
• D. Sciatica

Answer: (C)

A collection of blood between the dura mater and the arachnoid membrane is called a subdural hematoma. This term matches exactly what the question defines: blood accumulating in the subdural space. It commonly results from head injury that tears bridging veins, and its appearance on imaging is typically a crescent-shaped bleed that can cross some areas it’s not confined by bone. This differs from subarachnoid hemorrhage, which is bleeding into the space between the arachnoid and pia mater; Parkinson's disease, a neurodegenerative movement disorder; and sciatica, nerve-related leg pain.
