CTICasesAsbestosis with Curvilinear Lines
Imaging findings
Chest CT shows calcified diaphragmatic/pleural plaques and subpleural curvilinear lines in the lower lung zones and middle lobe, indicating early asbestos-related lung fibrosis (asbestosis).
Key takeaways
Subpleural curvilinear lines are early markers of asbestos-related pulmonary fibrosis (asbestosis). Their presence, along with calcified pleural plaques, helps differentiate asbestosis from early idiopathic pulmonary fibrosis.
