作者报告4例脑室内颅咽管瘤并有透明隔改变,这一表现既往文献未予注意。横断及冠状CT检查,3例颅咽管瘤表现为三脑室内无钙化、实体性强化肿块,1例显示为第三脑室内有钙化的囊性肿块。其中3例有透明隔变短、增厚并有强化,手术证实透明隔有胶质增生,但无肿瘤侵犯。另1例透明隔两叶明显分离。作者指出,颅咽管瘤通常起于灰质结节和垂体漏斗内残遗的麟状上皮细胞,偶可起于终板或灰质结节而完全位于三脑室内。三脑室内颅咽管瘤使透明隔发生反应性胶质增生,从而使透明隔增厚、强化,大的肿瘤也可造成透明隔两叶
The authors report 4 cases of intracranial craniopharyngioma with a transseptal change that was not previously noted in this literature. Transcranial and coronary CT examination, craniopharyngioma in 3 cases showed no intracranial calcification, solid enhancement mass, 1 case showed calcification cystic mass in the third ventricle. Three of them had a shorter translucency, a thicker thickened, and a glimpse of ophthalmology confirmed by surgery, but no tumor invasion. Another case of clear separation of two leaves clear. The authors note that craniopharyngiomas typically arise from remnant of epithelial cells in the gray matter and pituitary funnels and can even be located entirely in the third ventricle from the endplate or gray matter nodules. Craniopharyngiomas of the three cerebral ventricle transparent gliosis reaction occurs, so that the transparent septal thickening, strengthening, large tumors can also cause a transparent two leaves
