| HSAS | hydrocephalus due to stenosis of aqueduct of Sylvius; hypertrophic subaortic stenosis |
| 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) |
| 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) |
