| 摘 要： | 目的探讨神经节细胞胶质瘤的MRI表现特点。方法回顾性分析20例经手术病理证实的神经节细胞胶质瘤患者的MR图像,其中男13例,女7例。全部病例均接受MR平扫及增强扫描,获得T1WI、T2WI及FLAIR图像及增强图像,分析MRI特点。结果所有病灶均为单发,位于幕上者16例,其中额叶3例,颞叶10例,顶叶1例,额颞叶及枕顶叶各1例,幕下4例。囊性病变5例,囊实性病变8例,实性病变7例（其中4例呈脑回样增厚改变）。MRI上肿瘤信号呈多样性,T1WI病变囊性部分均呈低信号,实性部分呈低信号12例、等信号2例、高信号1例;T2WI囊性部分均呈高信号,实性部分呈等信号3例、高信号12例;瘤周多无水肿或轻度水肿,增强扫描病变实性部分及壁结节无强化4例,轻度强化5例,明显强化者6例。囊性病变囊壁强化2例,不强化3例。结论部分神经节细胞胶质瘤的MRI表现具有一定的特征性,结合临床,对部分病例可以作出正确诊断。

| Abstract: | Objective To analyze the MRI features of cerebral ganglioglioma. Methods MR imaging features of ganglioglioma in 20 cases(13 male and 7 female) confirmed by operation and histopathologic examination were analyzed retrospectively. Precontrast and contrast MR scan were performed in 20 patients. T1WI, T2WI, fluid attenuated inversion recovery (FLAIR) and contrast enhancement images were obtained. Results All cases were solitary,16 lesions were supratentorial, 4 lesions subtentorial. Among them, 3 lesions were ... |
