摘要

目的：探讨中枢神经系统肠源性囊肿的影像学表现。方法：收集经手术病理证实的肠源性囊肿12例，分析其影像学表现。结果：桥前池、桥小脑角池2例，脊髓腹侧髓外硬膜下间隙9例，背侧髓外硬膜下间隙1例，“脊髓嵌入症”8例。1例CT平扫等脑脊液密度。8例T1WI、T2WI类似脑脊液信号；3例T1WI、T2WI信号混杂。增强扫描，仅1例边缘轻度半环状强化。结论：中枢神经系统肠源性囊肿影像学表现具有一定的特征，MRI具有一定的诊断价值。

Abstract

Objective:　To study the imaging features of enterogenous cysts in central nervous system. Methods:　The clinical data including 12 cases of neurenteric cyst confirmed by surgery and pathology were collected and analyzed. Results:　In the 2 intracranial cases, lesions located in anterior pontine cistern, the remaining 10 intraspinal cases were in intradural-extramedulla space, among which, 9 occurred in cervical segments, 1 in lumbar segment, 9 located anterior to the spinal cord and 1 posterior. In the intraspinal cases, 8 cases showed spinal cord incuneation. 9 cases showed isointense to CSF, 3 cases showed slightly hyperintense than CSF on T1WI, heterogenous hyperintense on T2WI, one lesion had restricted diffusion. All lesions had no enhancement on postcontrast images. Conclusion:　To certain extent, the image manifestation of enterogenous cysts in central nervous system is characteristic, and MRI can make a correct diagnosis preoperatively.
