A case of round pneumonia due to Enterobacter hormaechei: the need for a standardized diagnosis and treatment approach in adults
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.
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
