CTICasesSubpleural Curvilinear Lines in Asbestosis
Imaging findings
Chest CT demonstrates calcified pleural plaques and early interstitial lung disease characterized by prominent subpleural curvilinear lines and subpleural dots representing peribronchial fibrosis in a patient with historical asbestos exposure.
Key takeaways
Subpleural curvilinear lines running parallel to the pleural surface are a classic CT sign of early asbestosis, helping distinguish it from idiopathic pulmonary fibrosis (IPF).
