Subdural Hematoma – Radiopaedia

Subdural Hematoma – Radiopaedia When bleeding occurs between the dura and the next layer, the arachnoid membrane, it's called a subdural hematoma. this bleeding occurs under the skull and outside the brain, not in the brain. Blood builds up between the brain and the brain's tough outer lining. the condition is also called a subdural hemorrhage. in a subdural hematoma, blood collects immediately beneath the dura mater. the dura mater is the outermost layer of the meninges. the meninges is the three layer protective covering of the brain. C subdural hematomas may take weeks to months to appear. these are more commonly seen in the elderly population where brain shrinkage stretches the blood vessels “bridging”. In a subdural hematoma, the blood seeps between the dura and the arachnoid layers. it collects inside the brain’s tough outer lining. this bleeding is often from a blood vessel that breaks within the space around the brain. this most often happens because of a head injury. the injury can be mild.
