CTICasesAsbestos-induced pleural plaques
Imaging findings
Chest CT shows multiple large, calcified parietal pleural plaques with adherent parenchymal bands (tethering the lung) causing pressure erosion and remodeling of the adjacent ribs, in a patient with a history of environmental asbestos exposure.
Key takeaways
Parietal pleural plaques are the most common manifestation of asbestos exposure. In rare cases where the visceral pleura is also involved and lung parenchymal bands tether the lung, the restricted lung motion can cause the growing plaques to erode or remodel the adjacent ribs.
