Acute and serial chest radiographic appearances of Q-fever in a large UK outbreak in the West Midlands are described. In 69 acute films (taken within 20 days of onset of illness), 10% of films were normal. Appearances in 62 abnormal films were varied and, in contrast to some previous reports, showed no features that might distinguish Q-fever pneumonia from pneumonias of other origins. Analysis of serial films in 47 cases showed that complete radiographic resolution frequently took up to 6 months, longer than has been described previously. Initial appearances deteriorated over the first 2 weeks of radiographic surveillance in 20% of cases. No relationship was found between the extent of radiographic change and the age of the patient or the presence or absence of respiratory symptoms. Age did not affect time to resolution.
本文描述了西米德兰兹郡一次大规模英国Q热疫情中患者胸部X线的急性表现及系列变化情况。在69份急性胸片（发病20天内拍摄）中，10%的胸片表现正常。62份异常胸片的表现各异，与之前的一些报告不同，未显示出可将Q热肺炎与其他病因所致肺炎相鉴别的特征。对47例患者系列胸片的分析显示，影像学完全恢复正常通常需要长达6个月的时间，比之前报道的时间更长。在20%的病例中，最初的表现会在影像学监测的前2周内恶化。未发现影像学变化程度与患者年龄或有无呼吸道症状之间存在关联。年龄不影响恢复时间。
