CTICasesRuptured rheumatoid lung nodules causing hydropneumothorax
Imaging findings
CT scan shows multiple thick-walled, cavitating subpleural nodules in the lower lobes. Serial scans show progression to pleural thickening, a persistent hydropneumothorax, and a bronchopleural fistula.
Key takeaways
Rheumatoid nodules typically occur in the subpleural regions of the lower lobes and are prone to cavitation. Rupture of a subpleural cavitary nodule into the pleural space can lead to a persistent, difficult-to-manage hydropneumothorax and bronchopleural fistula.
