目的探讨中枢神经系统肠源性囊肿的 MRI 特征,以提高鉴别诊断水平.资料与方法7例经手术病理证实的中枢神经系统肠源性囊肿患者均行 MR 平扫加增强扫描,分析其特征性的 MRI 表现.结果7例中枢神经系统肠源性囊肿中,6例位于椎管内硬脊膜下脊髓腹侧,1例位于松果体区.MRI 显示病变信号均匀, T1WI 呈低信号,6例稍高于脑脊液信号,1例与脑脊液信号等信号;T2WI 呈高信号.增强扫描显示,5例无强化,1例囊肿边缘轻度强化,1例囊壁环形强化.结论中枢神经系统肠源性囊肿有其特征性的 MRI 表现,MRI 检查对发现及诊断本病具有重要价值.

Purpose To investigate the MRI manifestations of enterogenous cyst in central nervous system, and to improve the diagnostic accuracy of this disease. Materials and Methods Seven cases of surgical pathology proven enterogenous cysts underwent MRI plain and enhancement scanning, the MRI features were analyzed. Results Six lesions located in the subdural extramedullary space, one lesion located in the pineal region. The signal was hypo or iso-intensity on T1WI and hyperintensity on T2WI. On post-contrast images, one showed circular enhancement, one was slightly peripheral enhancement, and no enhancement was observed in the other five cases. Conclusion The MRI manifestation of enterogenous cyst in central nervous system is characteristic. MRI plays an important role in its diagnosis.
