title: Developmental tumour of the visual pathways. Report of an unusual case.
abstract: An unusual case of congenital hydrocephalus and visual loss due to developmental tumour of optic pathways is described. Diffuse, uniform and symmetrical replacement and enlargement of optic nerves, chiasma and optic tracts resulted in remarkable computerized tomographic (CT) scan images not yet described in the literature. Embryo-pathogenesis of this anatomical configuration of the neoplasm outlining the enlarged visual pathways in their entirety is discussed. The relevant literature is reviewed.
