| 摘 要： | 目的分析2例乳头状胶质神经元肿瘤（PGNT）同时复习文献，归纳总结其影像表现。方法使用GE公司3．0T磁共振扫描仪对1名12岁女性及1名27岁男性PGNT患者进行MR平扫及增强扫描，分析2例患者的临床表现、MRI特点及病理特征，并对文献资料进行归纳总结。结果2例患者临床表现为失神发作和癫痫。MRI表现为囊实性病变及囊性病变伴壁结节，增强扫描后实性部分及壁结节明显强化。2例均位于颞叶，其中1例与侧脑室关系密切。病理镜下可见特征性的假乳头结构和双相分化的神经胶质细胞及神经元。结论PGNT的MRI表现以囊性肿块伴壁结节多见，病灶位置多靠近脑室且与脑室关系密切，脑室旁型和脑室外型的分类有助于诊断。

| Abstract: | Objective To analyze the magnetic resonance imaging (MRI) and pathological features of papillary glioneuronal tumor (PGNT) in 2 patients and review the literature. Methods A 12-year-old female and a 27-year-old male underwent pre-and post-contrast MRI with a 3.0 T magnetic resonance scanner (GE Service). The clinical, MRI and pathological features of PGNT were analyzed. The literature was reviewed. Results The clinical symptoms include absence seizure and epilepsy. MRI showed a cystic solid mass or a cystic... |
