| ABSTRACT |
|
The concepts of hydrocephalus can be applied at all conditions in which the intracranial volume of the cerebrospinal fluid(CSF) is abnormally large in relation to the volume of the brain.
The pathology of progressive hydrocephalus can only be understood on the basis of the anatomy of the CSF pathway, the sites of its production and absorption. Whatever are the causes, these seem to be five distinct ways in which hydrocephalus may occur 1) by an overproduction of CSF 2) by an obstruction to the out-flow of CSF 3) by obstruction in the communicating channels 4) by failure in development of or obstruction in the main absorption mechanism 5) by an increase in the protein content of the CSF.
Neuroradiological investigations in the form of ventriculography and angiography are valuable before the introduction of computed tomography of brain(CSF). Nowdays, brain CT is available as a non-invasive and accurate diagaostic method. |
