Organizing pneumonia. (a) Axial and (b) coronal images in lung windows in a 43-year-old man with a history of follicular lymphoma demonstrate predominantly peripheral ground-glass opacities (arrow). The patient had undergone chemotherapy and was admitted for respiratory failure. Lung biopsy yielded organizing pneumonia. The patient did well on steroids and was discharged.

COVID 19 69-year-old male presents with a fever and a cough. CXR findings reveal vague right upper lung zone and left lower lobe changes question early consolidation. The CT scan confirms the presence of confluent extensive ground glass change in the superior segment of the right lower lobe and bilateral, nodular, and peripheral ground glass and opacification in the lower lobes. These findings are consistent with but not diagnostic with the diagnosis of COVID 19. Differential diagnosis however includes other viral pneumonias, allergic alveolitis and other multifocal and organizing pneumonias.

Atoll Sign with Peribronchovascular Thickening and GGO – DDx COP (Path Proven) Axial CT of the chest in a 55-year-old female with a subacute cough demonstrates bronchovascular bundle thickening (yellow arrows )and foci of consolidation (white arrows) and ground-glass opacities (GGO(blue arrow) ) in the superior segment of the right lower lobe (RLL). Notably, this opacity exhibits the “atoll sign” (green star)—a central area of GGO (blue arrow) surrounded by denser peripheral consolidation (red arrow)—considered a characteristic feature of cryptogenic organizing pneumonia (COP). COP often manifests with patchy, peribronchial or peripheral consolidation, migratory opacities, and subpleural sparing. The differential diagnosis includes COP, subacute infection, non-specific interstitial pneumonia (NSIP), and hypersensitivity pneumonitis. In this case, COP was confirmed by biopsy, reinforcing its position as the leading diagnosis. Ashley Davidoff MD – TheCommonVein.com (140577L)
