Diagnostic Challenge and Treatment Delay in Drowning-Associated Pneumonia: A Case of Combined <i>Aeromonas</i>, <i>Legionella</i>, and <i>Aspergillus</i> Infection.

ABSTRACT: Drowning-associated pneumonia often involves multiple types of pathogens, including Aeromonas hydrophila, Legionella spp., and fungi. We report the case of an 82-year-old man who developed a rare combined infection with these three organisms after freshwater drowning. Initial therapy for typical aspiration pneumonia was ineffective. Although A. hydrophila and Legionella pneumophila were subsequently identified and targeted, the patient's condition failed to improve. While chest computed tomography on the 11th day of hospitalization revealed worsening infiltrates and new cavity lesions, bronchoscopy was delayed until Day 13 due to circulatory instability. Subsequently, Aspergillus fumigatus was identified from bronchial lavage. Despite starting targeted antimicro
