8F-FDG-PET-CT was performed in a 58-year-old man with unexplained fatigue and weight loss. PET (not shown) showed a lesion in the left apex with moderate uptake, corresponding on CT with a 1.2 cm spiculated nodule. On the axial CT-image in lung window setting a some fine linear strands extending to the pleura (pleural tags) are noted.
