CTICasesChronic Pleural Thickening and Rounded Atelectasis post Lung Transplant
Imaging findings
CT chest in a lung transplant recipient shows progressive, diffuse thickening of both the visceral and parietal pleural membranes in the right hemithorax, with associated subpleural consolidations showing a comet-tail sign, consistent with rounded atelectasis.
Key takeaways
Pleural complications are common after lung transplantation. Chronic pleuritis and pleural thickening can develop, leading to local lung entrapment and the formation of rounded atelectasis. Rounded atelectasis can mimic a pulmonary mass and is characterized by a subpleural mass with bronchovascular bundles curving into it (comet-tail sign).
