An epidural hematoma is primarily associated with traumatic injury that results in the tearing of an extradural artery, often the middle meningeal artery. This type of hematoma typically occurs following a blow to the head, which can cause a skull fracture and disrupt the arterial supply. The arterial bleed occurs between the skull and the dura mater, accumulating quickly and leading to increased intracranial pressure.

This mechanism explains why a sudden impact can lead to rapid deterioration in a patient’s neurological status, which is a hallmark of this condition. The accumulation of blood can also create a lens-shaped mass on imaging studies, distinguishing it from other types of hematomas. Understanding this pathology is essential for timely diagnosis and intervention in clinical situations involving head trauma.
