Severe Hospital-acquired Pneumonia Caused by Pan-resistant Acinetobacter Baumannii with Septic Shock in a Postoperative Patient: A Case Report

Abstract

Hospital-acquired pneumonia (HAP) is one of the most common nosocomial infections encountered in Intensive Care Units (ICUs) and is associated with high morbidity and mortality rates, particularly when caused by multidrug-resistant (MDR) pathogens such as Acinetobacter baumannii (1,2). We report the case of a 68-year-old woman with a cerebellopontine angle (CPA) tumor who developed severe HAP caused by pan-resistant A. baumannii during hospitalization. The diagnosis was established through the integration of clinical, radiological, and microbiological findings. Despite the administration of broad-spectrum antibiotics and adequate intensive care management, the patient’s condition progressively deteriorated and ultimately resulted in death. This case highlights the importance of clinical vigilance, early diagnosis, and appropriate therapeutic strategies in managing MDR infections.
