HRCT findings in OP
- Bilateral peripheral consolidations, sharply demarcated.
- Consolidations may be migratory.
- Lesions may show pleural tags or spiculae and give the impression of volume loss and slight retraction of the surrounding parenchyma (DD bronchogenic carcinoma).
- Bronchial wall thickening and dilatation are seen in most patients and are usually restricted to areas of consolidation or ground glass opacifications.
- Additional findings are pleural thickening, small pleural effusions and parenchymal bands.

After exclusion of other diseases such as lymphoma, infection, bronchoalveolar carcinoma, the diagnosis of cryptogenic organizing pneumonia was made. #Clinical #Radiology #CTChest #COP #Cryptogenic #Organizing #Pneumonia #ILD #RadiologyAssistant
