| hydrocephalus | A condition marked by dilatation of the cerebral ventricles, most often occurring secondarily to obstruction of the cerebrospinal fluid pathways and accompanied by an accumulation of cerebrospinal fluid within the skull, the fluid is usually under increased pressure, but occasionally may be normal or nearly so. It is typically characterised by enlargement of the head, prominence of the forehead, brain atrophy, mental deterioration and convulsions, may be congenital or acquired and may be of sudden onset (acute h.) or be slowly progressive (chronic or primary b.). Origin: Gr. Kephal = head (18 Nov 1997) |

| hydrocephalus ex vacuo | Hydrocephalus due to loss or atrophy of brain tissue; less commonly associated with raised intracranial pressure. (05 Mar 2000) |
| noncommunicating hydrocephalus | Hydrocephalus secondary to a block in cerebrospinal fluid flow in the ventricular system or between the ventricular system and spinal canal. Synonym: noncommunicating hydrocephalus. (05 Mar 2000) |
| normal pressure hydrocephalus | <neurology> A brain disorder caused by blockage of the flow of cerebrospinal fluid (CSF), with enlargement of the ventricles of the brain (keep the pressure normal) and compression of brain tissue. Brain atrophy is the result. In this condition the CSF is produced normally but not reabsorbed. Symptom onset is gradual. A key feature is dementia. Treatment is surgical (VP shunt). (13 Nov 1997) |
| double compartment hydrocephalus | Independent supra-and infra-tentorial hydrocephalus usually due to a veil occlusion of the aqueduct of Sylvius. (05 Mar 2000) |
| infantile hydrocephalus | <radiology> A VP-Shunt Can Decompress The Hydrocephalic Child, Aqueductal stenosis, Vein of Galen aneurysm, Postinfectious, Superior vena cava obstruction, Chiari malformation, Dandy-Walker syndrome, Tumour, Haemorrhage, Choroid plexus papilloma see: hydrocephalus (12 Dec 1998) |
| internal hydrocephalus | Hydrocephalus in which the accumulation of fluid is confined to the ventricles; also occurs as an autosomal recessive condition in the Hereford and Holstein breeds of cattle. (05 Mar 2000) |
| obstructive hydrocephalus | Hydrocephalus secondary to a block in cerebrospinal fluid flow in the ventricular system or between the ventricular system and spinal canal. Synonym: noncommunicating hydrocephalus. (05 Mar 2000) |
| occult hydrocephalus | <neurology> A brain disorder caused by blockage of the flow of cerebrospinal fluid (CSF), with enlargement of the ventricles of the brain (keep the pressure normal) and compression of brain tissue. Brain atrophy is the result. In this condition the CSF is produced normally but not reabsorbed. Symptom onset is gradual. A key feature is dementia. Treatment is surgical (VP shunt). (13 Nov 1997) |
| otitic hydrocephalus | A form of thrombotic hydrocephalus associated with otitis media and thrombosis of one or both transverse sinuses of the dura. (05 Mar 2000) |
| thrombotic hydrocephalus | Increase in cerebrospinal fluid and of intracranial pressure following thrombosis of the cerebral veins or sinuses; caused by septic infection, dehydration, tuberculosis, typhoid, leukaemia, and other conditions. (05 Mar 2000) |
| toxic hydrocephalus | Thrombotic hydrocephalus associated with some general infection or toxic state. (05 Mar 2000) |
| external hydrocephalus | Accumulation of fluid in the subarachnoid spaces of the brain, accumulation of fluid in the subdural space owing to a persistent communication between the subarachnoid and subdural spaces. (05 Mar 2000) |
| spina | Synonym: vertebral column. Origin: L. A thorn, the backbone, spine (05 Mar 2000) |
| spina angularis | A posterior and downward projection from the greater wing of the sphenoid bone on either side, located posterolateral to the foramen spinosum, so-named for its proximity to the sphenoidal spine; gives attachment to the sphenomandibular ligament. Synonym: processus spinosus, spina ossis sphenoidalis, alar spine, angular spine, spina angularis, spinous process. (05 Mar 2000) |
