Organizing pneumonia is a nonspecific pulmonary response pattern associated with a variety of clinical contexts including viral infections. The classic radiological manifestations are peribronchovascular/peripheral ground glass opacities or consolidations and may be accompanied by nodules, masses, and interstitial opacities. We describe the case of a 62-year-old male patient with SARS-CoV-2 pneumonia and torpid clinical and radiological evolution in whom organizing pneumonia was documented through transbronchial biopsy and imaging findings, with a good response to corticosteroids. The importance of recognizing the development of organizing pneumonia lies in the better prognosis and outcome in those patients who receive treatment with corticosteroids, however, the clinical and radiological suspicion must be confirmed with biopsy because radiological findings associated with bacterial coinfection may overlap.
机化性肺炎是一种与多种临床情况相关的非特异性肺部反应模式，包括病毒感染。典型的放射学表现为支气管血管周围/外周磨玻璃影或实变，可能伴有结节、肿块和间质影。我们描述了一例62岁男性SARS-CoV-2肺炎患者，其临床和放射学进展缓慢，通过经支气管活检和影像学检查发现了机化性肺炎，对皮质类固醇治疗反应良好。认识到机化性肺炎的发生的重要性在于，接受皮质类固醇治疗的患者预后和结局较好，然而，临床和放射学怀疑必须通过活检来证实，因为与细菌合并感染相关的放射学表现可能重叠。
