Subdural Hematoma

This images depicts a craniotomy for the evacuation of a subdural hematoma. A subdural hematoma occurs when there is significant bleeding that occurs between the surface of the brain and the dura (outermost part of the meninges). Usually, a tearing of a bridging vein may cause significant bleeding leading to the hematoma shown above. Severe mass effect and pushing of the lateral ventricles can be seen on proper imaging.
