| 摘 要： | 目的：探讨颅底软骨肉瘤的MRI表现特点。方法：搜集6例经手术病理证实的颅底软骨肉瘤，分析其MR表现。结果：6例病灶分布散在，肿瘤所附着处颅底骨质破坏，局部可见大小不等肿块，多可见分叶，边界多数较为清晰，邻近脑组织无或有轻度水肿。MRI显示病灶信号欠均匀，T1WI以等信号为主，内可见斑片状更低信号区，T2WI则以高信号为主，其中混杂散在低信号或更高信号区，增强后肿瘤为不均匀的显著强化，病灶内T1WI、T2WI均为低信号区，增强后无强化。结论：颅底软骨肉瘤在MR上能够准确地进行定位诊断，其MRI表现具有一定的特点。

| Abstract: | Objective:To study the MRI features of chondrosarcoma at cranial base.Methods:MRI findings of 6 cases with chondrosarcoma at cranial base verified by operation and pathology were analyzed.Results:Foci in all 6 cases distributed in a scattered way.There was bony destruction at cranial base where tumor was located.The tumor showed small or large mass and most of them were lobulated with clear margin.Brain tissue nearby showed no or mild edema.The signal intensity of lesions was inhomogeneous.Tumors showed mai... |
