摘　　要：目的:探讨颅内节细胞胶质瘤的MRI表现特点。方法:回顾性分析8例经手术病理证实的颅内节细胞胶质瘤的MRI表现,并结合其临床及病理进行分析。结果:病灶均为单发。7例位于幕上,其中额叶3例、顶叶2例,枕叶1例,侧脑室1例;1例位于幕下(位于小脑)。肿瘤结构形式多样,MRI表现可分囊性为主型和实性为主型,其中囊实性病灶6例,实性病灶2例。多数病例水肿占位效应不明显,增强后肿瘤强化呈多样性。结论:颅内节细胞胶质瘤有相对特征性的MRI表现,结合临床,对某些较典型的病变应该考虑到本病的可能。Objective:To investigate the MRI features of intracranial ganglioglioma.Methods:MR imaging,clinical and pathological features of gangliogliomas in 8 cases were analyzed retrospectively.Results:All cases were solitary.7 lesions were supratentorial,in which 3 lesions located frontal lobe,parietal lobe 2 cases,occipital lobe 1 case,1 lesions situated in the subtentorial region(in the cerebellum).Gangliogliomas may be divided into solid tumors and cystic tumors on the basis of their MR characteristics,in which 6 lesions were showed with cystic-solid pattern,2 lesions with solid.Peritumoral edema were not obvious for most tumors.On enhanced MRI,tumors may be various pattern enhancing.Conclusion:Gangliogliomas may present with some characteristic MRI findings.Some cases of cerebral ganglioglioma can be suggested in combination with clinical manifestation.
