COVID-19 Case Complicated with Organizing Pneumonia and Pneumothorax: Correspondence

TO THE EDITOR—Organizing pneumonia on imaging may be seen as unilateral or bilateral peripheral peribronchovascular ground glass or air space consolidation, large nodules commonly with consolidation, or in some patients, peripheral consolidation. The bilateral consolidation typically has subpleural extension without subpleural sparing. Subpleural sparing is typically seen in chronic lung disease such as nonspecific interstitial pneumonitis (NSIP). Other descriptions are of a nodule with a reverse halo (atoll sign), where a ground glass nodule is surrounded by a rim of consolidation.
