Intracranial Hemorrhage

About Intracranial Hemorrhage

Intracranial hemorrhage refers to bleeding within the skull that can occur in various locations including the brain parenchyma, subarachnoid space, subdural space, or epidural space. This condition represents a neurological emergency requiring immediate intervention, as increased intracranial pressure can lead to brain herniation and death. Common causes include trauma, hypertension, aneurysm rupture, arteriovenous malformations, and anticoagulant use.

Pathophysiology

Bleeding within the intracranial space leads to increased intracranial pressure due to the rigid, non-expandable nature of the skull according to the Monro-Kellie doctrine. As blood accumulates, it compresses brain tissue, reduces cerebral perfusion pressure, and can cause midline shift or herniation syndromes. The location of hemorrhage determines specific pathophysiologic consequences, with parenchymal bleeds causing direct tissue damage while extraaxial hemorrhages primarily cause mass effect.

Clinical Reasoning

Clinical presentation varies by hemorrhage location and severity, ranging from sudden severe headache and altered mental status to focal neurological deficits and coma. Rapid neurological assessment using tools like the Glasgow Coma Scale, along with emergent CT imaging, guides immediate management decisions. Treatment priorities include airway protection, blood pressure control, reversal of coagulopathy when present, and neurosurgical consultation for potential evacuation or monitoring of intracranial pressure.
