静脉注射海洛因所致胸部病变的影像学表现

目的 探讨静脉注射海洛因所致胸部感染性病变的影像学方法。方法 回顾性分析25例静脉注射海洛因继发胸部感染性病变患者的临床与影像学资料。尿海洛因试验均阳性，均摄有高kV胸片，6例做了胸部CT扫描，6例做了超声心动图检查。结果 胸部X线平片及CT上表现为肺纹理增多5例，小片状模糊影15例，肺气囊16例，小空洞16例，小结节7例，胸腔积液8例，气胸2例，液气胸6例，肺水肿2例；心影增大11例，多种形态病灶并存20例。6例超声心动图检查者，见三尖瓣赘生物4例，三尖瓣关闭不全4例。结论 静脉注射海洛因的胸部感染性病灶影像表现多种多样，其中“多发小空洞和肺气囊征”对青壮年静脉注射海洛因所致肺部感染的诊断有一定的价值。

Imaging of chest disease due to intravenous heroin abuse

Objective To study the imaging findings of the chest disease due to intravenous heroin abuse. Methods Twenty five cases of clinically confirmed chest disease due to intravenous heroin abuse were retrospectively analyzed. 25 cases had conventional X ray film, 6 cases had CT scanning, and 6 cases had echocardiography scanning. Results On X ray and CT, the following signs were found: lung making manifold ( n =5), small patchy shadow ( n =15), pneumatocele ( n =16), small cavity ( n =16), small node ( n =7), pleural effusion ( n =8), pneumothorax ( n =2), hydropneumothorax ( n =6), pulmonary edema ( n =2), megacardia ( n =11), multiple shaped lesion ( n =20). On echocardiography, tricuspid vegetation ( n =4) and tricuspid insufficiency ( n =4) were found. Conclusion The X ray and CT manifestations of chest inflammation due to intravenous heroin abuse are multiple. The multiple small cavities and pneumatoceles sign are of some value in the diagnosis of lung inflammation due to intravenous heroin abuse among young patients.
