**Core Concept**
Extradural hematoma (EDH) due to burns involves a complex interplay between thermal injury, coagulopathy, and bone fragility, leading to a specific set of clinical and radiological features.

**Why the Correct Answer is Right**
EDH due to burns is characterized by the presence of a biconvex or crescent-shaped extradural collection, often associated with a depressed skull fracture. This is due to the fact that the heat generated by the burn injury causes coagulation of the blood in the extradural space, leading to the formation of a hematoma. The biconvex shape is a result of the pressure exerted by the hematoma on the surrounding brain tissue.

**Why Each Wrong Option is Incorrect**
* **Option A:** Cerebral edema is a common feature of burns, but it is not a characteristic feature of EDH due to burns.
* **Option B:** Skull fracture is a common cause of EDH, but the specific type of fracture associated with burns is more likely to be a depressed fracture.
* **Option D:** Increased intracranial pressure is a feature of EDH due to burns, but it is not the correct answer as it is not a distinguishing feature of this specific type of EDH.

**Clinical Pearl / High-Yield Fact**
Burns can cause a coagulopathy that increases the risk of EDH, making it essential to monitor patients with severe burns for signs of intracranial hemorrhage.

**Correct Answer:** A.
