58-year-old woman with right lower lobe nodule on (A) present lung cancer screening CT, and (B) lung cancer screening CT performed 2-years prior. The nodule was described as a growing pure ground glass nodule (associated with a cystic lesion), measuring 15 mm in mean diameter. The nodule was categorized as Lung-RADS 3 by the clinical report, though as Lung-RADS 2 by strict application of size criteria. Subsequent wedge resection demonstrated lepidic-predominant adenocarcinoma.
