A 28-year old man presented with decreased vision and a bitemporal hemianopia. Magnetic resonance (MR) imaging demonstrated what appeared to be an enlarged optic chiasm and, on T2-weighted images, hypersignal extending along the optic tracts. This was felt to represent an intrinsic chiasmal mass, most likely a chiasmal glioma. Biopsy specimens from the first craniotomy were nondiagnostic. With continued visual failure, the patient underwent a second operation, and the correct diagnosis of craniopharyngioma was established. This article emphasizes the difficulties encountered with neuroradiologic evaluation and histopathologic study of craniopharyngioma.
一名28岁男性出现视力下降和双颞侧偏盲。磁共振成像显示视交叉似乎增大，在T2加权图像上，高信号沿视束延伸。这被认为代表一种原发性视交叉肿物，最可能是视交叉胶质瘤。首次开颅手术的活检标本未明确诊断。由于视力持续下降，患者接受了第二次手术，最终确诊为颅咽管瘤。本文强调了颅咽管瘤在神经放射学评估和组织病理学研究中遇到的困难。
