Chronic subdural hematoma
A chronic subdural hematoma is a collection of blood on the brain's surface, under the outer covering of the brain (dura). Almost all chronic subdural hematomas result from modest cranial trauma. The hemorrhage is not present on early imaging of the posttraumatic brain but usually develops at least 21 weeks after the injury. The most frequent presenting symptoms are headache, cognitive decline, gait abnormalities, and hemiparesis.
