Case Presentation:
A 60-year-old man was referred to a pulmonologist evaluation with persistent dyspnea and cough 1 month after discharge for an acute respiratory failure caused by Legionella pneumophila pneumonia, which required invasive mechanical ventilation. Chest CT scan performed during hospitalization showed lobar consolidation of upper left lobe (Fig 1A). Bronchial culture revealed L pneumophila; the patient was treated with levofloxacin and supported with invasive mechanical ventilation for 2 weeks. Chest radiograph after extubation showed almost complete resolution of infiltrates. After 1 month, the patient still complained of dyspnea and a new chest CT scan was performed: the consolidation migrated (Fig 1B; Video 1).

Definition: It is defined by specific criteria based on blood gas measurements. Hypoxemia happens when the partial pressure of oxygen (PaO2) falls below 60 mmHg. At the same time,...
