Organizing pneumonia pattern in the follow-up CT of Legionella-infected patients.
The main aim of this study was to describe the appearance of the CT pattern of organizing pneumonia in Legionella-infected patients. Serial CT scans obtained from five sporadic cases of Legionella pneumophila pneumonia were retrospectively reviewed. The mean time of follow-up was 14 days. Chest CT was analyzed with regard to frequency and appearance of CT patterns of pulmonary abnormalities. Consolidation and ground-glass opacities, with or without an air bronchogram, were the most common abnormalities detected in CT scans during follow-up patients with L. pneumophila pneumonia. Two patterns were observed: subpleural and peribronchovascular. The subpleural pattern was seen in four patients and the peribronchovascular pattern in one. Interlobular septal thickening was seen in one patient. Pleural effusion was seen in one patient. The CT pattern of organizing pneumonia, a subpleural pattern, was frequently observed after treatment of L. pneumophila pneumonia.
