摘要
目的分析颅咽管瘤的CT及MR表现,并探讨其病理及其在临床手术中的意义。方法回顾性分析123例经手术病理证实的颅咽管瘤的CT、MR影像表现及病理,研究相关的手术资料。结果男70例,女53例。年龄1～72岁,平均23.82岁。其中成釉质细胞型59例,鳞状乳头型41例,混合型23例。18例表现为实体瘤,38例为囊性瘤,钙化78例,23例肿瘤后部与三脑室壁间分界不清,影像学发现垂体柄11例,术中发现垂体柄53例。结论MRI有助于显示肿瘤范围及周围组织的解剖关系;CT对钙化的显示优于MRI;应用影像学技术显示肿瘤的部位、钙化形式、辨识垂体柄及与下丘脑的关系对于优化手术方案至关重要。
Objective To analyze the CT and magnetic resonance imaging （MRI） findings of craniopharygioma and explore the correlation between the pathological findings and clinical features of the disease. Methods The CT and MRI findings of 123 pathologically confirmed craniopharygioma cases were reviewed retrospectively in conjunction with the pathological findings and surgical data. Results This patient cohort consisted of 70 male and 53 female patients with their age ranging from 1 to 72 years （mean 23.82 years）. Of the 123 craniopharyngioma patients, 59 were found to have adamantinous craniopharyngiomas, 41 had papillary squamous craniopharyngiomas, and 23 had mixed tumors. Solid tumor was found in 18 cases, cystic tumor in 38 cases, and calcification in 78 cases; in 23 cases, the posterior of the tumor did not exhibit clear boundary from the wall of the three cerebral ventricles, and in 11 cases CT and MRI displayed hypophysial stalk, which was found intraoperatively in 53 cases. Conclusions MRI allows clear vision of the range of craniopharyngioma involvement and the anatomical structures surrounding the tumor. CT, on the other hand, shows better performance in displaying the calcification foci. Accurate identification of the site, dimension, calcification patterns and relation between the hypophysial stalk and hypothalamus by the imaging modalities significantly benefits the optimization of the surgical plan for the tumor.
