Subdural Hematoma | Anatomy, Etiology, Pathophysiology, Clinical Features, Treatment

Official Ninja Nerd Website: https://ninjanerd.org Ninja Nerds! In this neuropathology lecture, Professor Zach Murphy presents a detailed breakdown of Subdural Hematoma (SDH)—a form of intracranial hemorrhage caused by rupture of bridging veins between the dura and arachnoid mater. This lecture helps you distinguish SDH from other brain bleeds while mastering this critical condition's clinical patterns, imaging features, and management strategies. We begin by reviewing the anatomy of the subdural space and how shearing forces—particularly from trauma, falls, or rapid deceleration—can lead to venous bleeding. You’ll learn how acute SDH presents with rapid neurological decline, while chronic SDH develops more insidiously, especially in elderly patients, alcoholics, or those on anticoagulation. The lecture discusses common symptoms, including altered mental status, headache, focal neurologic deficits, and, in severe cases, signs of increased intracranial pressure or herniation. Unlike epidural hematomas, we explain how to interpret non-contrast CT scans, emphasizing the classic crescent-shaped hyperdensity that can cross suture lines. Management depends on the size and clinical impact—ranging from close observation in stable patients to emergency surgical evacuation (e.g., burr hole or craniotomy) in cases with mass effect or neurologic deterioration. We also discuss the importance of reversing anticoagulation and monitoring for reaccumulation. Enjoy the lecture and support us below!
