The subdural space (or subdural cavity) is an artificial space created by the separation of the arachnoid mater from the dura mater as the result of trauma, pathologic process, or the absence of cerebrospinal fluid as seen in a cadaver. The arachnoid matter normally adheres to the dura mater due cerebrospinal fluid within the subarachnoid space. In the cadaver, due to the absence of cerebrospinal fluid, the arachnoid mater falls away from the dura mater. It may also be the site of trauma, such as a subdural hematoma, causing abnormal separation of dura and arachnoid mater. Hence, the subdural space is referred to as "potential" or "artificial" space.
