【摘要】：目的:分析大脑皮层及皮层下NOS型胶质母细胞瘤的MRI表现及其临床意义。方法:搜集15例主体位于大脑皮层并经手术病理证实的NOS型胶质母细胞瘤患者的术前常规MR图像,结合文献进行回顾性分析。结果:15例均表现为团块样病灶,位于额叶最多见,瘤体主要呈长T1、长T2信号,信号不均匀,8例在平扫T1WI上病灶内可见高信号区。增强后13例表现为显著不均匀环形或蜂房样强化,其中6例可见脑膜受侵、强化,瘤体内轻度坏死4例(27%),轻度瘤周水肿7例(47%);轻度强化2例(13%)。结论:大脑皮层及皮层下NOS型胶质母细胞瘤具有一些较典型的MRI特征。
[Abstract]:Objective: to analyze the MRI features and clinical significance of NOS type glioblastoma in cerebral cortex and subcortex. Conventional Mr images of 15 patients with NOS type glioblastoma, whose main body was located in the cerebral cortex and proved by surgery and pathology, were collected. Results 15 cases showed mass lesions, most of which were located in the frontal lobe. The tumor showed long T 1, long T 2 signal intensity and uneven signal intensity. Hyperintense areas could be seen in the lesions on T1WI in 8 cases. After enhancement, 13 cases showed significantly inhomogeneous circular or honeycomb enhancement, and 6 cases showed meningeal invasion and enhancement. There were 4 cases of mild necrosis in the tumor and 7 cases of mild peritumor edema. Conclusion: cerebral cortex and subcortical NOS glioblastoma have some typical MRI features.
