Chronic Subdural Hematoma

Chronic Subdural Hematoma
Chronic SDH becomes low density as the hemorrhage is further reabsorbed. It is usually uniformly low density but may be loculated. Rebleeding often occurs and causes mixed density and fluid levels.
Crescent shaped chronic subdural hematoma (arrowheads). Notice the low attenuation due to reabsorbtion of the hemorrhage over time.
This chronic subdural hematoma (arrowheads) shows the septations and loculations that often occur over time.
