From: Pathologic N0 Status in Clinical T1N0M0 Lung Adenocarcinoma is Predictable by the Solid Component Proportion with Quantitative CT Number Analysis

Figure 1

Images of a 59-year-old female patient with invasive adenocarcinoma (a–d) and a 45-year-old male patient with invasive adenocarcinoma (e–h). (a,b) The lung window and mediastinal window of the axial HRCT showed a partially solid nodule in the left upper lobe. (c) The CT number distribution curve revealed that the solid component proportion of the nodule was 6%. (d) The photomicrograph (hematoxylin and eosin staining; magnification × 20) revealed a lepidic-predominant invasive adenocarcinoma consisting of 80% lepidic pattern and 20% acinar pattern (pT1N0M0). (e,f) The lung window and mediastinal window of the axial HRCT showed a solid nodule in the right upper lobe. (g) The CT number distribution curve revealed that the solid component proportion of the nodule was 80.3%. (h) The photomicrograph (hematoxylin and eosin staining; magnification × 100) revealed an acinar-predominant invasive adenocarcinoma consisting of 80% acinar pattern and 20% solid pattern (pT1N2M0, right superior mediastinal lymph node metastasis, 3/6; subcarinal lymph node metastasis, 1/1).
