Subdural hematomas are a type of traumatic brain injury that involves a brain bleed that occurs within the skull, outside of the brain tissue. They can occur at any age and affect 21 in every 100,000 individuals, but are most commonly seen in the elderly population. They can occur for a variety of reasons such as trauma or underlying health conditions. Subdural hematomas occur due to a collection of blood in the subdural space between the dura and arachnoid mater. Computed tomography is the best imaging modality to diagnose subdural hematomas due to the short scan times, and the ability to produce cross sectional images. Subdural hematomas are classified into categories based on the location and appearance of the bleed. These classifications can include acute, subacute, and chronic. Treatment is dependent on the location and classification of the subdural hematoma and may involve observation or surgical intervention. The overall prognosis is patient dependent and considers the size and classification of the bleed. A timely diagnosis with successful intervention is key for patient survival.
