摘　　要：目的：分析不同种类肿瘤颅底侵犯的ＣＴ表现。方法：３２例起源于不同组织的肿瘤（７例良性，２５例恶性）均有颅底侵犯。ＣＴ扫描使用Ｐｈｉｌｉｐｓ～ｔｏｍｏｓｃａｎ３５０型全身ＣＴ扫描机，层厚３～６ｍｍ，所有病例均有轴位扫描，１５例同时有冠、矢状位扫描。结果：颅底侵犯的部位、范围与肿瘤起源部位和性质有密切关系，３２例中２０例有颅内侵犯，ＣＴ特征为颅内外肿物相连续且密度一致，未见瘤内出血、坏死，较少发生瘤周水肿。结论：轴、冠状位ＣＴ扫描是肿瘤颅底侵犯诊断与定位的主要方法。矢状位扫描可做为诊断的辅助方法。Objective: To analyze CT features of base of skull involoed by various kinds of neoplasms. Methods: 32 neoplasms(7 benigns 25 malignants)which originated fiom different tissuses and invaded the base of skull were performed on Philips-Tomoscan 350 CT systems.The section thickness was 36 mm.Transverse images obtained in all patients.Sagittal and coronal images obtained in 15 of them. Results: The location and extent of base of skull involved by neoplasms were related to the origin and nature of neoplasms 20 cases had intracranial extension,CT images showed that intracranial masses connected with extracranial masses and the intensity of masses were identical both intracranial and extracranial masses.There were no hemorrhage and necrosis in tumors and less encephaloedema around masses. Conclusions: The cross and coronal CT casns are mainly methods for diagnosis and location of base of skull iuvolued by neaplasms.while the sagittal CT scan is onily a compensatory method.
