Official Ninja Nerd Website: https://ninjanerd.org Ninja Nerds! In this high-yield neuropathology lecture, Professor Zach Murphy breaks down the key features of an Epidural Hematoma, a life-threatening neurosurgical emergency caused by bleeding between the skull and dura mater, most often due to traumatic rupture of the middle meningeal artery. This lecture connects anatomy, clinical presentation, and imaging to help you recognize and respond to this critical condition. We begin by reviewing the anatomy of the epidural space and the vascular structures at risk in skull fractures, particularly the temporal bone. The lecture highlights how arterial bleeding leads to rapid hematoma formation, which, if not treated emergently, can cause increased intracranial pressure and brain compression. You’ll learn the classic clinical presentation: head trauma followed by a transient lucid interval, then rapid neurological deterioration as the hematoma expands. We explain the pathophysiologic progression of brain herniation and why prompt recognition is essential. We observe the hallmark findings on non-contrast CT scan, including the characteristic biconvex (lentiform) hyperdense shape, typically limited by suture lines. Management strategies focus on emergent neurosurgical evacuation, usually via craniotomy, and supportive care to prevent secondary brain injury. Enjoy the lecture and support us below!
