lat·er·al ven·tri·cle

[TA]
a cavity shaped somewhat like a horseshoe in conformity with the general shape of the cerebral hemisphere; each lateral ventricle communicates with the third ventricle through the interventricular foramen of Monro, and expands from there forward into the frontal lobe as the anterior horn as well as caudally over the thalamus as the central part (cella media) or body that, behind the thalamus, curves anteriorly and laterally, then forward into the temporal lobe as the inferior horn; from the apex of the curve (the atrium of the lateral ventricle) a variably sized posterior horn extends back into the white matter of the occipital lobe. The large choroid plexus of the lateral ventricle invades the body, atrium, and inferior horn (but not the anterior and posterior horns) from the medial side.

First described by Hakim and Adams in 1965, idiopathic normal pressure hydrocephalus (INPH) is an enlargement of cerebral ventricles (Fig 1) without evidence of chronic increased intracranial pressure (ICP).
In INPH, as CSF gradually increases in volume, dilating the cerebral ventricles (Fig 1), brain tissue is compressed, acting as a temporizing mechanism to maintain ICP within a normal range.
