Lung Abscess Caused by <i>Pseudomonas aeruginosa</i> after a Near-drowning Episode

of 1.0) was initiated. His respiratory condition gradually improved, and he was transferred to the general ward. However, on day 10 of hospitalization, the patient developed a fever. Chest computed tomography (CT) revealed a new cavity in the right upper lobe, which was suggestive of a lung abscess. Ceftriaxone was initiated but was ineffective. Sputum culture on day 10 revealed Pseudomonas aeruginosa, and cefepime was subsequently administered. His fever resolved, and follow-up CT on day 23 showed marked improvement in the cavity and surrounding consolidation. Due to suspected cefepime-induced acute kidney injury, the antibiotics were switched to moxifloxacin, and the patient was discharged on hospital day 28. Following macroaspiration events, clinicians should evaluate the risk of pneumonia and likely pathogens. In patients who develop pneumonia after near-drowning, empirical coverage of Gram-negative organisms, including P. aeruginosa, should be considered.
