目的探讨静脉滥用海洛因致肺部感染的临床及影像学表现特征。方法回顾性分析56例静脉注射海洛因致肺部感染患者的病历资料,重点观察其临床及影像学表现特征。结果临床表现主要为不同程度的呼吸系统感染症状和体征,以金黄色葡萄球菌感染为主;影像学表现主要有肺纹理粗重、肺实变、空洞和肺气囊、结节、胸膜改变、单一改变、多改变并存,分别占30.4%、80.4%、75.0%、42.9%、19.6%、21.4%、78.6%。结论肺部感染是静脉滥用海洛因主要感染形式,感染以化脓性肺炎最多见;肺纹理粗重、肺实变、空洞和肺气囊、结节、胸膜改变是其肺部感染较特征性的影像表现。
Objective To investigate the clinical and imaging features of heroin-induced pulmonary infections. Methods A retrospective analysis of 56 cases of intravenous injection of heroin-causing pulmonary infection in patients with medical records, focusing on clinical and imaging findings. Results The main clinical manifestations were respiratory symptoms and signs of different degrees, with Staphylococcus aureus infection mainly. The main imaging findings were gross lung mass, lung consolidation, voids, lung balloon, nodules and pleura, single change , Changing more coexist, accounting for 30.4%, 80.4%, 75.0%, 42.9%, 19.6%, 21.4% and 78.6% respectively. Conclusions Pulmonary infection is the main form of heroin infection by intravenous injection. The infection is the most common in septic pneumonia. The gross lung mass, lung consolidation, voids, and air sacs, nodules and pleura changes are the characteristic images of lung infection.
