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。

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.
