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.
