| Summary: | ABSTRACT Round pneumonia is an unusual radiological manifestation of a bacterial lung infection. We present the case of an elderly male patient who arrived at the emergency room with a productive cough and exertional dyspnea. His chest x-ray and CT showed a round opacity and air bronchograms in the right upper lobe. Taken together, the patient’s symptoms and images strongly suggest a pulmonary infection. Empirical antibiotic therapy with ceftriaxone and clarithromycin was started. The sputum culture was positive for Enterobacter hormaechei and the bacterium was sensitive to levofloxacin; therefore, the antibiotic therapy was changed. Despite the treatment, the patient progressed to respiratory failure and septic shock, dying six days after admission. Although round pneumonia is uncommon, it is a potentially curable disease and clinicians should always consider it in their differential diagnosis. |
