Abstract

Altitudinal hemianopias may be related to chiasmatic involvement. A case in which horizontal inferior hemianopia is associated with a tumor in the posterior fossa producing a triventricular hydrocephalus is described. The visual field defect is interpreted as a consequence of the pressure by a dilated third ventricle upon the chiasmatic area.

Key-words

altitudinal hemianopia internal hydrocephalus posterior fossa tumor 

Sommario

Viene descritto un caso di emianopsia altitudinale bilaterale inferiore associata ad un tumore in fossa cranica posteriore che determina un idrocefalo triventricolare. L'inusuale difetto campimetrico viene interpretato come dovuto alla compressione esercitata sul chiasma da parte del terzo ventricolo dilatato.
