摘　　要：目的:认识高位心包上隐窝的CT表现,及其对诊断与鉴别诊断的意义。材料与方法:回顾性分析500例因各种原因进行肺部多排螺旋CT扫描,对怀疑有高位心包上隐窝者进行多平面重建,经几名经验丰富的医师最后确认,统计高位心包上隐窝的出现率及描述特征性表现并测量大小。结果:9例最后被确诊为高位心包上隐窝,占1.8%。横轴位图像最长径57.38mm,平均20.31mm;最长短经31.85mm,平均12.23mm,表现为气管前右侧旁区多边形、半月形、卵圆形、圆形和三角形水样密度影,冠状位及矢状位最长径平均约为47.6mm,呈长条状,上部盲端呈囊袋状,往下紧贴无名动脉和升动脉壁,并与常见部位心包上隐窝相连。结论:多排螺旋CT薄层及多平面重建可更好地观察高位心包上隐窝解剖结构、形态及密度,故更有把握与纵隔或心包病变相鉴别诊断。Purpose： To meet high pericardium fossae on CT manifestations, and its significance in diagnosis and dif- ferential diagnosis. Materials and Methods ： a retrospective analysis of 500 cases for various reasons in the lungs more row helical CT scans, for suspected high on the pericardium fossae multiplanar reconstruction, confirmed by several experienced doctors finally, statistical fossae on high cardiac rate and characteristic description and size measurement. Results： 9 cases was finally diagnosed with high fossae on the pericardium, accounting for 1.8%. Transverse image the longest diameter 57.38 mm, the average 20. 31 mm; The length of the 31.85 mm, 12. 23 mm on average, show the trachea right next to the area be- fore the polygon, half moon, ovoid, circle and triangle watery density shadow, coronal and sagittal an average of about 47. 6 mm, the longest diameter are long strips, upper pouch shaped blind end, down close to the unknown and higher artery wall, and is connected to a common site on the pericardium fossae. Conclusion： more row spiral CT thin layer and muhiplanar re- construction can better observe high pericardium fossae on anatomical structure, shape and density, so the more be sure with mediastinal disguised differential diagnosis or cardiac disease.
