There is diffuse left hemithorax nodular pleural thickening encasing the lung and with, perhaps, some left hemithorax volume loss. A component of pleural effusion cannot be excluded. Three small coils projected within the left hemithorax infer previous surgical intervention. The right lung and pleural space are clear. Enlarged left paratracheal stripe either represents lymphadenopathy or pleural mass component.
Chasing for previous imaging or further CT recommended.
