肺栓塞X线胸片误诊分析（附14例报告）

目的分析肺栓塞X线胸片表现和误诊原因。方法经临床诊断为肺栓塞患者14例,所有患者均行X线胸片及下肢深静脉彩超,其中8例行CT平扫及CTA,4例行MRI平扫及3D CE MRI。结果 X线胸片：14例中10例诊断为肺炎,2例诊断为胸膜炎,2例诊断为肺癌并肺不张和胸腔积液。其X线表现为10例（71.4%）病变区有不同程度的肺纹理减少,肺野透亮度增加;12例（85.7%）肺实质可见片状浸润阴影,其中6例病变位于肺野外带或肺表面贴近胸壁,病灶单发或多发;6例（42.9%）见少量胸腔积液及胸膜增厚;4例（28.6%）膈肌上抬;2例（14.3%）两侧肺门影增大;2例右下肺动脉（14.3%）增宽。MRI：1例右心房内见软组织信号团块影,另3例患者主肺动脉及左下肺动脉呈线样狭窄或充盈缺损,远端分支减少。8例CTA显示左或右下肺动脉管腔不规则充盈缺损,肺动脉分支减少。下肢深静脉彩超发现12例患者有深静脉血栓形成。结论多数PE胸片表现没有特异性,但综合分析其异常X线表现并结合临床可减少误诊。对可疑患者需动态随访,观察其胸片变化情况或行CTA、3D CE MRI或DSA检查。

Analysis of misdiagnosis of pulmonary embolism on chest radiography

Objective To analyze the findings on chest radiography and misdiagnostic causes of pulmonary embolism.Materials and Methods Imaging features of 7 patients with clinically-diagnosed pulmonary embolism retrospectively analyzed.Results All cases were misdiagnosed on chest radiography.10 cases were misdiagnosed as pleural effusion plus pneumonia;2 case was misdiagnosed as pleural effusion;and 2 case was misdiagnosed as peripheral lung cancer.Abnormal signs were seen on plain chest film of all the cases,includin...
