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.
本文描述了一例因视路发育性肿瘤导致先天性脑积水和视力丧失的罕见病例。视神经、视交叉和视束的弥漫性、均匀性和对称性替代及增大，产生了文献中尚未描述的显著计算机断层扫描（CT）图像。本文讨论了肿瘤这种解剖结构的胚胎发病机制，该机制勾勒出了整个扩大的视觉通路。并对相关文献进行了综述。
