摘要
目的：本文目的是对后颅窝囊肿的ＣＴ－ＭＲ影像学的诊断作用进行评价。材料与方法：１２例后颅窝囊肿的ＣＴ和ＭＲ影像表现进行了分析，探讨了其与临床表现和类型的相关性。结果：本组病例包含Ｄａｎｄｙ－Ｗａｌｋｅｒ囊肿（５例）、蛛网膜囊肿（３例）和巨枕大池（４例），ＣＴ和ＭＲ都可提供无创性检测手段。结论：ＣＴ和ＭＲ二者对后颅窝囊肿的诊断均有效，但在显示病变的性状、大小和轮廓方面。
Objective: To evaluate the diagnostic value of posterior fossa cyst with CT MR imaging.Materials and Methods: Appearances of CT and MR imaging in 12 patients with posterior fossa cysts were analyzed and correlated with the clinical findings and types.Results: The patients presented in this series included Dandy-Walker cyst (5 cases), arachnoid cysts (3 cases) and mega cisterna magna (4 cases). CT and MR imaging may provied a noninvasive means of identifying these pathological entities.Conclusion: Both of CT MR imaging are valuable in the diagnosis of posterior fossa cyst where the nature, size, and the contour of the cyst, MR is showed more accuracy than that of CT.
