This is an example of an acute subdural hematoma. Blood is located outside the brain, but inside its covering, the dura. The white appearance indicates the bleeding was recent.
Medical management includes supportive care such as airway protection and fluid replacement, giving medicine to reverse any anticoagulants, keeping the head of the bed elevated to help lower the pressure inside the head, and close monitoring.
Large subdural hematomas require a craniotomy to remove the clot and stop the bleeding.
The patient’s outcome is predicted best by their condition before surgery.
