【摘要】 目的:研究椎管内肠源性囊肿的MRI特征表现。材料与方法:搜集6例经手术病理证实的椎管内肠源性囊肿的资料,分析其MRI表现,其中男4例,女2例,年龄12～26岁,平均17岁。均行轴位T1WI成像,矢状位T1WI、T2WI成像。结果:4例位于颈胸交界处,1例位于颈段,1例位于胸段,6例囊肿均位于椎管中线部位,与脑脊液相比T1WI,囊内容物等信号4例,稍高信号2例,T2WI等信号。结论:MR可以清楚地显示肠源性囊肿,根据其信号特点和位置,可提示肠源性囊肿的诊断。更多还原

【Abstract】 Objective: To study the MR imaging features of intraspinal enterogenous cysts. Materials and Methods: Six cases of surgically-proven enterogenous cysts were reviewed and their MR imaging features were analyzed(four were male and two were female, age ranged from twelve to twenty-six, with a mean of seventeen years). All cases evaluated by MR with axial section on T1WI and sagittal section on T1WI and T2WI. Results: Four cysts were in the junction of thoraco-cervical spine, one cyst was in the cervical spine, one cyst was in the thoracic spine, all cysts were located in the midline. Six cysts were either isointense(4 6) or slightly hyperintense(2 6) compared to CSF on T1WI. All were isointense to CSF on T2WI. Conclusion: Enterogenous cysts are best delineated by MR imaging. On the base of MR signal features and its location, the lesion is suggestive of the diagnosis.更多还原
