提要分析了１４例病理证实的颅咽管瘤ＣＴ表现。肿瘤位于鞍上者５例，跨鞍上与鞍内者９例。囊性者１１例呈边界清楚的低密度占位，环形、半环形强化或不强化，常伴有团状或蛋壳样钙化。实性３例呈不规则形或弥漫增大形，混合密度或高密度，不均匀／岛状强化。并讨论了颅咽管瘤的起源与发生、临床表现及预后、ＣＴ表现的病理基础以及鞍区肿瘤的鉴别诊断。 Abstract 14 cases of pathologically confirmed CT manifestations of craniopharyngioma were analyzed. The tumors were located in the saddle in 5 cases, across the saddle and saddle in 9 cases. 11 cases of cystic lesions were clearly defined low-density space occupying, annular, semi-circular enhanced or not, often accompanied by clumps or eggshell-like calcification. Solid in 3 cases were irregular or diffuse increased shape, mixed density or high density, uneven / Island enhanced. The origins and occurrences of craniopharyngiomas, their clinical manifestations and prognosis, the pathological basis of CT findings and the differential diagnosis of tumors in the sellar region were discussed.
