**Core Concept**
Subdural hematoma is a type of intracranial hemorrhage characterized by bleeding into the space between the dura mater and the arachnoid mater, leading to increased intracranial pressure and potential brain herniation. This condition often results from traumatic head injury, but can also be caused by anticoagulation or other vascular disorders.

**Why the Correct Answer is Right**
Subdural hematoma is typically located in the cerebral convexity, and the blood accumulates in the dependent portion of the subdural space, often along the falx cerebri or tentorium cerebelli. This condition is more common in older adults and individuals with pre-existing coagulopathy. The clinical presentation may include headache, vomiting, and altered mental status, and the diagnosis is often confirmed by non-contrast computed tomography (CT) or magnetic resonance imaging (MRI).

**Why Each Wrong Option is Incorrect**
**Option A:** Subdural hematoma is typically caused by a tear in the middle meningeal artery, which is not accurate. The middle meningeal artery is more commonly associated with epidural hematoma.
**Option B:** Subdural hematoma is often seen in the cerebral sulci, which is not entirely accurate. While it can occur in the cerebral sulci, the blood typically accumulates in the dependent portion of the subdural space.
**Option C:** Subdural hematoma is always associated with a skull fracture, which is not true. While skull fracture can be a contributing factor, it is not a necessary condition for subdural hematoma to occur.

**Clinical Pearl / High-Yield Fact**
A key aspect of managing subdural hematoma is recognizing the importance of early surgical intervention, particularly in cases where there is significant mass effect or evidence of herniation. Prompt evacuation of the hematoma can help alleviate pressure and prevent further complications.

**Correct Answer:** D.
