Incidental finding in a 48-year-old man. Axial CT in lung window setting shows a small round somewhat spiculated 7 mm nodule in the right lower lobe. The nodule clearly shows a bronchial interruption sign with abrupt cut-off of the bronchus running towards the nodule. Morphological findings are highly suspicious for a small primary lung cancer. 18F-FDG-PET showed moderate uptake in the nodule as well as in the left adrenal gland. Histopathologic examination of the adrenal gland showed a non-small cell lung cancer metastasis
