HRCT and pathological characteristics of a 72-year-old female patient with lepidic-predominant adenocarcinoma. (a) CT image showed a pGGN located in the right upper lobe with nonlobulated border and unclear tumor-lung interface (black arrow). (b) CT image showed that mean diameter was measured by calculating mean of longest diameter of nodule and its perpendicular diameter in same maximum view. (c) Photomicrograph of histopathologic specimen showed tumor cells lining preexisting alveolar structures with alveolar septum thickening (black arrow), foci of invasive components was more than 5 mm in thickness (white arrow).
