摘　　要：目的　探讨Tornwaldt囊肿的MRI特征。方法　回顾性分析 145 2例包括鼻咽部的头部MR图像 ,年龄自 1个月至 82岁 ,平均 5 5 .7岁。观察Tornwaldt囊肿的信号强度、形状和大小。结果145 2例中发现 18例Tornwaldt囊肿 ,占 1.2 4%。 18例病变在T2 WI上均与脑脊液呈等信号 ,T1WI上病变信号高于肌肉。 13例病变呈圆形 ,5例呈椭圆形 ,病变最大径自 2～ 15mm不等 ,15例显示鼻咽存在不同程度腺体增生。结论　Tornwaldt囊肿在日常头部MRI中占 1 2 4% ,在T1WI上高于肌肉信号 ,T2Objective To evaluate Tornwaldt′s cyst using MR imaging. Methods 1 452 cases with head MR imaging were reviewed. The signal intensity, shape, and size of the lesions were observed. Results Tornwaldt′s cyst were found in 18 of 1 452 cases (1 24%), all of the 18 cases were isointense to CSF on T 2WI and hyperintense to muscle on T 1WI.Tornwaldt′s cyst were round ( n =13)and ovoid ( n =5). The size of lesions were from 2 mm to 15 mm. There were 15 cases with adenoid hyperplasia. Conclusions Tornwaldt′s cysts occupied 1 24% in routine head MR imaging and were hyperintense to muscle on T 1WI and isointense to CSF ON T 2WI.
