Right apical lung cancer in a 71-year-old man. (a) Low-dose axial CT scan shows small irregular fibrotic changes of the right apex (arrow). (b) One year later, LDCT shows a slight increment of the focal abnormalities with the typical aspect of apical fibrotic changes, with a pleural tag and concomitant emphysema (arrow). (c) Two years later, a remarkable increment in size was clearly depicted (arrow) and the lesion has been surgically removed with a diagnosis of lung adenocarcinoma
