EDH least common possibility is in
**Core Concept**
Extradural hematoma (EDH) is a type of intracranial hemorrhage characterized by the accumulation of blood between the dura mater and the skull. It is often caused by a traumatic head injury, leading to laceration of the middle meningeal artery.
**Why the Correct Answer is Right**
The correct answer is in a location where the middle meningeal artery is less likely to be damaged. The middle meningeal artery is located in the epidural space and runs along the inner surface of the skull. In individuals with a congenitally small or absent mastoid air cell, the middle meningeal artery may be more superficial and less protected, making it more susceptible to injury. However, this is not the correct answer. The correct answer is in a location where the middle meningeal artery is even more protected.
**Why Each Wrong Option is Incorrect**
**Option A:** Temporal bone - This is a common location for EDH, as the middle meningeal artery runs along the inner surface of the temporal bone.
**Option B:** Occipital bone - The occipital bone is also a common location for EDH, as it is a part of the posterior cranial fossa where the middle meningeal artery may be damaged.
**Option C:** Frontal bone - The frontal bone is another common location for EDH, as it is a part of the anterior cranial fossa where the middle meningeal artery may be damaged.
**Clinical Pearl / High-Yield Fact**
The location of the middle meningeal artery is more protected in the posterior cranial fossa, particularly in the occipital bone. This is because the occipital bone is thicker and more robust than the temporal or frontal bones, providing greater protection to the middle meningeal artery.
**Correct Answer: D.**
