Epidural hematoma

An epidural hematoma is a blood collection between the dura mater and the calva. In the supratentorial space, it most often arises on the basis of arterial bleeding, most often by bleeding from the artery meningea media. In the infratentorial region, venous sinuses are often the source of bleeding. [1] It is rather rare at the age of 60, because the dura mater clings firmly to the bone.
