Figure 3

CT image of patient. (a) Pulmonary window; (b) mediastinal window; (c, d) arterial phase and venous phase: nodules in the apical segment of the right upper lobe, about 19 ∗ 16 mm in size, with lobulated edges and burrs, relatively uniform density, CT value of about 13–30 HU, visible blood vessels Cluster sign and pleural depression sign, bronchiectasis is seen around, the enhancement scan is unevenly enhanced, the solid part is obviously enhanced, and the CT value is about 43–60H; (e, f)lymph nodes, moderately enhanced on contrast-enhanced scan (arrows).
