ABSTRACT
In an 86-year-old man with a history of chronic obstructive pulmonary disease and prostate cancer who had been in close contact with his cats, chest radiography and computed tomography revealed an asymptomatic consolidation in the left lower lobe. A bronchofiberscopy was performed to investigate the patient’s worsening radiographic findings. Pasteurella multocida was identified in the bronchial lavage fluid and was considered to be an etiological agent of pulmonary consolidation. Radiographic findings improved after antibiotic treatment. Although the patient subsequently experienced several recurrent asymptomatic infections and received antibiotic treatment at the same site, the consolidation in the left lower lobe disappeared after he stopped keeping his cats. Close contact with animals can cause P. multocida pulmonary infections in patients with respiratory diseases or those in an immunosuppressive state. Careful post-treatment observation is thus essential.
