Cough
Patient Data
Age: 65 years
Gender: Male
Frontal

Unfolded aorta. Lungs clear. Irregular dense linear process deep to left lateral rib cage. Lungs clear.
Coronal bone window

Single CT image confirms pleural calcification on left lateral pleural surface. No pleural plaques or calcification elsewhere. Review on other windows showed no signs of asbestos-related lung disease.
Case Discussion
The presence of a solitary, albeit large, unilateral focus of pleural calcification points more to causes such as previous hemothorax and pleural infection than to calcification of asbestos-related plaques.
