目的:探讨Rathke囊肿的诊断价值。方法:回顾性分析4例经病理证实的Rathke囊肿患者临床、CT、MRI资料。结果:4例患者均接受CT、MRI检查,CT检查示均为等密度或稍高密度结节呈圆形或椭圆形,边缘光滑锐利。2例为鞍内结节,2例为鞍内、鞍上结节,4例鞍区结节均无明显强化。MRI检查示结节T1WI低、等、高信号,T2WI等或稍高信号,1例结节增强扫描边缘强化,3例结节无强化。结论:CT、MRI是术前诊断Rathke囊肿的重要手段。
Objective: To investigate the diagnostic value of Rathke’s cyst. Methods: The clinical, CT and MRI data of 4 pathologically confirmed Rathke cysts were retrospectively analyzed. Results: All the 4 patients underwent CT and MRI examination. CT showed that the nodules were isosceles or slightly higher density. The nodules were round or oval, and the edges were smooth and sharp. 2 cases of intra-saddle nodules, 2 cases of saddle, suprasellar nodules, 4 cases of saddle nodules were not significantly enhanced. MRI showed nodules T1WI low, etc., high signal, T2WI or slightly higher signal, enhanced nodule enhanced scan edge in 1 case, nodular enhancement in 3 cases. Conclusion: CT and MRI are important methods for preoperative diagnosis of Rathke cyst.
