Pre-operative CT chest images of 71-year-old active smoker (55 pack years) who underwent right upper lobectomy for suspicious lung nodule showing: a subpleural reticular changes (arrow) and centrilobular ground glass opacities (arrowhead) consistent with interstitial lung abnormality and b traction bronchiectasis (arrow) and centrilobular emphysema (asterisk). Non-malignant histologic findings for this patient included emphysema, histologic fibrosis, respiratory bronchiolitis and peribronchiolar metaplasia (not shown). Additionally, pre-surgical CT chest images of a 58-year-old active smoker (30 pack years) who underwent right lower lobe lobectomy for suspicious lung nodule showing a CT pattern of combined pulmonary fibrosis emphysema (CPFE): c centrilobular and paraseptal emphysema (arrows) in upper lobes, and d reticular changes with honeycombing (arrow) in the right lower lobe.
