Multifocal areas of nodular consolidation and ground glass opacity in a predominantly peribronchial and subpleural distribution, slightly worse in the upper lobes demonstrated. No cavitation, intrapulmonary mass or significant collapse seen.
Tiny bibasal pleural effusions. A few small pretracheal nodes, however no evidence of hilar, mediastinal, supraclavicular or axillary lymphadenopathy.
Heart and pericardium are within normal limits. No pericardial effusion. Visualised upper abdominal organs are unremarkable. High-density material in the stomach and duodenum noted of uncertain significance. No bony destructive lesions seen in visualised spine, ribs or shoulder girdle.
Conclusion: multifocal nodular consolidation and ground glass opacity subpleural and peribronchial in distribution very suggestive of COP. It would be important to correlate with time post BMT. Other differentials, such as atypical fungal infection such as aspergillosis, are thought less likely.
