Abstract

Acinetobacter baumannii is a significant pathogen in nosocomial infections, especially in intensive care units. However, community-acquired A. baumannii (CAAB) pneumonia is an uncommon disease. Most of the CAAB pneumonia in the literature is characterized by an abrupt onset and rapid progression to respiratory failure and hemodynamic instability. In our case, a 51-year-old man without underlying diseases developed severe pneumonia. Respiratory distress rapidly worsened and mechanical ventilation was applied. Extra-corporeal membrane oxygenation was applied due to refractory septic shock. Fully sensitive A. baumannii pneumonia was confirmed by the sputum culture and blood culture. The patient was effectively treated by the meropenem. However, the patient died of uncontrolled ventilator-associated pneumonia, developed on the 10th hospital day, and refractory septic shock. We report the case of severe CAAB pneumonia with bacteremia in a patient without underlying diseases in Korea.

(A) Chest X-ray shows consolidation on the left lower lung field. (B) Chest CT shows consolidation and ground glass opacity on both lower lung fields. (C) Chest X-ray shows that consolidation on left lung field was aggravated three hours after admission. (D) Chest X-ray shows that bilateral diffuse infiltration was aggravated on the 2^nd hospital day. (E) Chest X-ray shows that bilateral diffuse infiltration was improved on the 7^th hospital day. (F) Chest X-ray shows that diffuse infiltration on the right lung field was aggravated on the 10th hospital day.
