▣Acinetobacter baumannii (AB) - Gram-negative coccobacillus - isolated only from infected patients, or from the hospital environment during outbreaks - important cause of hostpital-acquired pneumonia(HAP) - multiple drug resistance isolates - a few reports of community-acquired AB pneumonia,
in patients with comorbidities in tropical or subtropical areas ▣Community-acquired AB pneumonia - fulminant course,
with an acute onset of dyspnea,

Materials and Methods
▣We identified 36 patients with culture-proven AB pneumonia over a 3-year period through the computerized infectious disease database .▣Hosptial acquired pneumonia (n=28)▣Sex: Male-Female ratio 20:8▣Age : 31-94 years,
median age 72.2 years
▣Community acquired pneumonia (n=8)▣Sex: Male-Female ratio 3:5▣Age : 58-86 years,
median age 71.9 years▣We retrospectively reviewed clinical history,
initial chest radiographs and CT scans and follow-up simple radiograph imaging findings of eight patients...
▣Chest radiographs ▣Bilateral patchy alveolar opacities: 5 patients ▣Focal alveolar opacity: 2 patients ▣Large loculated pleural effusion: 1 patient ▣CT ▣Bilateral multifocal consolidations: 4 patients ▣Patchy ground glass opacity: 3 patients ▣Patchy peribronchial small branching nodular opacities: 1 patient ▣Pleural effusion: 3 patients (1 patient: pleural empyema) ▣Reactive mdiastinal nodes: 3 patients ▣In 4 patients,
rapid progression of diffuse parenchymal opacities suggesting ARDS was...
▣Bilateral patchy consolidation and ground glass opacities were the most common findings of community-acquired AB pneumoniaon chest ragiograph and CT.
Rapid progression of the consolidation to involve the whole lung fields within a week was notedin 4 patients among 8 patients ofcommunity-acquired Acinetobacter pneumonia. ▣Although these findings are not specific for AB pneumonia and the incidence of community-acquired AB pneumonia is low,
AB pneumonia should be included in the possible cause...
