目的探讨静脉注射海洛因致继发性金黄色葡萄球菌肺炎的临床和影像学表现特点。方法16例25～45岁男性,均有不洁注射海洛因史,均具有急性肺部感染的症状和体征,身体其他部位均未查及感染灶,白细胞均高于正常,全部病例做X线胸片,5例加做螺旋CT。以回顾性分析方法分析资料。结果全部患者尿海洛因试验呈阳性,血培养均有金黄色葡萄球菌生长。影像学发现肺实变12例,肺气囊12例,空洞6例,胸膜病变6例,多有2种以上影像学表现同时存在。并发右心内膜炎4例,病毒性肝炎5例,贫血5例。结论本组病例临床和影像学表现与非吸毒性继发性金黄色葡萄球菌肺炎相似,但身体其他部位无感染灶,合并症较多,肺气囊较多见。
Objective To investigate the clinical and imaging features of heroininduced secondary Staphylococcus aureus pneumonia. Methods Twenty-six male patients aged 25-45 years with unclean history of heroin injection all had symptoms and signs of acute pulmonary infection. No other lesion was found in the body and the white blood cells were higher than normal. All the cases were performed X-ray chest Film, 5 cases plus spiral CT. Retrospective analysis method to analyze the data. Results All patients had positive urine heroin test, and Staphylococcus aureus grew in blood culture. Imaging findings of 12 cases of lung consolidation, 12 cases of lung balloon, empty hole in 6 cases, 6 cases of pleural disease, and more than 2 kinds of imaging findings exist at the same time. 4 cases of concurrent right endocarditis, viral hepatitis in 5 cases, 5 cases of anemia. Conclusions The clinical and imaging findings of this group are similar to those of secondary non-drug-induced staphylococcus aureus pneumonia, but there are no focal lesions in other parts of the body with more comorbidities and pneumocystis is more common.
