title: Radiographic patterns in the diagnostic approach to organizing pneumonia.
abstract: A 56-year-old woman, non-smoker, who complained of dry cough and dyspnea during the last month came to the emergency department due to increased dyspnea. The chest X-ray showed areas of poorly defined, bilateral alveolar opacities, leading to the diagnosis of bronchopneumonia with partial respiratory failure. During admission, she experienced an exacerbation of the dyspnea. A high-resolution computed tomography scan was performed, showing areas of ground glass opacities with interlobular septal thickening ("crazy-paving" pattern), predominantly in lower lobes. She required mechanical ventilation and she was admitted to the intensive care unit. Subsequently, an open lung biopsy was performed. The following questions should be proposed:
