Organizing pneumonia (OP) is a distinct clinical and pathologic entity. The purpose of this study was to describe the clinical features at onset and outcome and the diagnostic approach in subjects with bronchiolitis obliterans-organizing pneumonia (BOOP). Differential diagnosis of interstitial lung diseases (ILDs) during the COVID-19 pandemic is difficult, due to similarities in clinical and radiological presentation between COVID-19 and other ILDs on the one hand, and frequent false-negative swab results on the other.

FOIA The classic radiological manifestations of organizing pneumonia are peribronchovascular/peripheral ground glass opacities or consolidations which can be migratory and may be accompanied by nodules, masses, and interstitial opacities. In clinical practice, OP occasionally presents as non-resolving pneumonia. Abstract In 50 of 94 patients with bronchiolitis obliterans we found no apparent cause or associated disease, and the bronchiolitis obliterans occurred with patchy organizing pneumonia. Malaise, cough, fever, dyspnea, bilateral alveolar infiltrates, and a restrictive pattern were the most common symptoms and findings. Marwah V, Peter DK, Sharma N, Bhattacharjee S, Hegde A, Shelly D, Malik V, Bhati G, Singh S. Lung India. Fibroblasts and collagen typify the histopathology of organizing pneumonia which is a regular reaction to lung injury. Persistent radiographic changes, including bilateral consolidations and associated ground glass opacities, were seen over a 6-month period, and pathology results from a wedge resection of the left lower lobe indicated an organizing pneumonia. Organizing pneumonia (OP) is a rare disease that is often easily misdiagnosed as a malignancy. Although certain laboratory abnormalities are more common in secondary OP and can be associated with worse prognosis, they are likely due to the underlying disease. We aimed to delineate the evolution of CT findings and outcome in OP of COVID-19.
