Three patients presenting with visual failure had MRIs with hypersignal extending from the region of the optic chiasm along both optic tracts in 2 cases, and along 1 optic tract in the 3rd. In all patients intrinsic tumor of the chiasm was the most likely diagnosis based on MRI appearances, but all 3 had craniopharyngioma.
三名出现视力减退的患者接受了磁共振成像（MRI）检查，其中2例显示高信号从视交叉区域沿双侧视束延伸，第3例沿1条视束延伸。根据MRI表现，所有患者最可能的诊断是视交叉原发性肿瘤，但3例均为颅咽管瘤。
