目的 探讨左房粘液瘤的影像学特征及其鉴别诊断价值。方法 分析 2 8例手术病理证实的左房粘液瘤的影像学表现 ,并且加以比较与鉴别。结果 1左房粘液瘤的 X线平片与二尖瓣狭窄略有相似 ,但其具有相对特征。2超声波能直接显示左房内团块状回声 ,并可观察瘤体随心动周期而活动情况。结论 在临床上当瘤体阻塞瓣口后产生类似二尖瓣狭窄的症状和体征 ,加之两者的 X线平片表现有相似之处 ,因而有时在鉴别诊断上较困难。超声心动图具有确诊价值 ,X线平片对于鉴别两者有一定价值
Objective To investigate the imaging features and differential diagnosis value of left atrial myxoma. Methods The imaging findings of 28 cases of left atrial myxoma confirmed by pathology were analyzed and compared. Results 1 X-ray film of left atrial myxoma was slightly similar to mitral stenosis, but it had relative characteristics. 2 Ultrasound can directly display the left atrial mass clonic echo, and can observe the activity of the tumor with cardiac cycle. Conclusion Clinically similar symptoms and signs of mitral stenosis occur when the tumor obstructs the orifice of the valve, and the X-ray plain film shows similarities between the two. Therefore, it is sometimes difficult to make a differential diagnosis. Echocardiography is of definite value, and X-ray film has a certain value for the identification of both.
