sub·du·ral space

originally thought to be a narrow fluid-filled interval between the dural and arachnoid; now known to be an artificial space created by the separation of the arachnoid from the dura as the result of trauma or some ongoing pathologic process; in the healthy state, the arachnoid is tenuously attached to the dura and a naturally occurring subdural space is not present.

sub·dur·al space

(sŭb-dūr'ăl spās) [TA]
An artificial space created by the separation of the arachnoid from the dura as the result of trauma or some pathologic process; in the healthy state, the arachnoid is tenuously attached to the dura and a naturally occurring subdural space is not present.

After evacuation and copious irrigation of the subarachnoid and subdural spaces, the remainder of the metastatic tumor not immediately underneath the craniectomy site continued to express this tumor-laden exudate, which now rapidly accumulated given the rapid and extensive decrease in intracranial pressure.

The hemorrhage, as previously stated, can diffuse into the subdural space of the spine and posterior fossa.
This can lead to arachnoepiduritis with reduced energy substrate delivery to the nerve roots, subsequent tissue edema, and creation of a real subdural space. The lack of prospective data collection and an ultimate clinical standard leave the definitive clinical identification of subdural injection uncertain [4].
Dural weakness, which maybe due to generalized connective tissue disorders such as Marfan\'s Syndrome, Ehler Danlos\' Syndrome Type-II, autosomal dominant polycystic disease, predispose to the formation of dural defects which allow CSF leakage into the epidural or subdural space.7-9 These dural tears or defects are easily observed during surgery, ranging from simple dural holes to complex fragile meningeal diverticula (seen in Marfan\'s Syndrome Patients) or even complete absence of the dura that normally covers the spinal nerve root.10 The volume of CSF leaking from a dural defect varies considerably.
However, a smooth, tan, firm mass was found layered in the subdural space. The dura was then opened in the parietal burr hole and similar findings were noted.

Subdural hematoma, also known as subdural hemorrhage, is a type of hematoma between the brain and the duramater, usually associated with traumatic brain injury, usually resulting from tears in bridging leptomeningeal veins which cross the subdural space. The clinical manifestations include headache, loss of consciousness, seizure, and irritability.
Collections in the subdural space, on the other hand, displace vessels towards the surface of the brain.
The low density band suggests the flow of the CSF into the subdural space, which indicates good outcome for patient with acute SDH1.
