| subdural | <anatomy> Situated under the dura mater, or between the dura mater and the arachnoid membrane. Source: Websters Dictionary (01 Mar 1998) |
| subdural cavity | 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 attached to the dura and a naturally occurring subdural space is not present. Synonym: spatium subdurale, cavum subdurale, subdural cavity, subdural cleavage, subdural cleft. (05 Mar 2000) |
| subdural cleavage | 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 attached to the dura and a naturally occurring subdural space is not present. Synonym: spatium subdurale, cavum subdurale, subdural cavity, subdural cleavage, subdural cleft. (05 Mar 2000) |
| subdural cleft | 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 attached to the dura and a naturally occurring subdural space is not present.

| subdural effusion | The leakage of cerebrospinal fluid into the subdural space. (12 Dec 1998) |
| subdural haematoma | <neurology, surgery> A serious type of head injury characterised by a collection of blood under the dura mater adjacent to the brain. Acute subdural haematomas are a surgical emergency that usually result from head trauma. (06 Mar 1998) |
| subdural haematorrhachis | haematorrhachis externa |
| subdural haemorrhage | Extravasation of blood between the dural and arachnoidal membranes; acute and chronic forms occur; chronic haematomas may become encapsulated by neomembranes. Synonym: subdural haematoma. (05 Mar 2000) |
| subdural hygroma | Accumulation in the subdural space of proteinaceous fluid, usually derived from serum, or of cerebrospinal fluid due to a tear in the arachnoid membrane. (05 Mar 2000) |
| subdural 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 attached to the dura and a naturally occurring subdural space is not present. Synonym: spatium subdurale, cavum subdurale, subdural cavity, subdural cleavage, subdural cleft. (05 Mar 2000) |
| empyema, subdural | An intracranial suppurative process between the dura and the arachnoid. The infection gains entrance to the subdural space from the frontal and ethmoid sinuses, the middle ear, and the mastoid cells. (12 Dec 1998) |
| subdural h. |
accumulation of blood in the subdural space. In the severe acute form, both blood and cerebrospinal fluid enter the space as a result of laceration of the brain and a tear in the arachnoid, adding subdural compression to the direct injury to the brain. In the chronic form, only blood effuses into the subdural space as a result of rupture of the bridging veins, usually due to closed head injury. The effusion is a gradual process resulting, weeks after the injury, in headache and progressive focal signs that reflect the location of the mass.
