ABSTRACT
Purpose The incidence and drug resistance rate ofAcinetobacter baumannii pneumonia are becoming more and more serious.To summarize the computed tomography (CT) appearance ofAcinetobacter baumannii pneumonia and to provide evidence for early clinical diagnosis and treatment.Materials and Methods The imaging findings of 49 patients with sputum culture confirmed Acinetobacter baumannii pneumonia were retrospectively analyzed,and the imaging features were summarized.Results The three most common patterns of chest CT findings in Acinetobacter baumannii pneumonia were ground-glass opacification (69.4％,34/49),consolidation (67.3％,33/49),and pleural effusion (53.1％,26/49).While,the most common patterns of chest X-ray were pulmonary plaque (83.7％,41/49),consolidation (36.7％,18/49),and pleural effusion (36.7％,18/49).Further analysis showed that there was no statistically significant difference in the CT and X-ray findings between combined infection of Acinetobacter baumannii with other pathogens and single Acinetobacter baumanniizxcvbnm,infection (P＞0.05).Conclusion The three most common changes of chest imaging of Acinetobacter baumannii pneumonia are ground-glass opacification,pulmonary consolidation and pleural effusion.It is of great significance to summarize its imaging features for early diagnosis,treatment and prognosis-predicting.
