摘要

A 56-year-old woman presented with blood-tinged sputum. A chest radiograph showed a nodule in the rightmid-lung zone. Chest computed tomography (CT) revealeda 1.6 cm well-demarcated nodule with eccentric calcification in the right middle lobe (Fig 1a). The lung windowsetting showed ground glass opacity (GGO) surroundingthe nodule, creating a halo sign (Fig 1b). An interveninglucent area between the nodule and GGO was also noted.The nodule was suspected as being benign (e.g. ahamartoma); however, associated findings, such as GGOand peritumoral lucent components, could not beexplained. On 2-[fluorine 18]fluoro-2-deoxy-D-glucose(FDG) positron emission tomography/CT, the nodule andGGO showed mild FDG uptake (maximum standardizeduptake value 1.7–2.0). The possibility of malignancy showing lepidic growth could not be excluded. Thus, a rightmiddle lobectomy was performed. Histopathological analysis revealed a well-circumscribed tumor with abundanthemorrhage. The tumor was composed of pneumocytesand round cells, suggesting pulmonary sclerosingpneumocytoma (PSP) (Fig 2a). TTF-1 and vimentin werepositive on immunohistochemical staining. The halo signon CT was correlated with hemorrhage in the lung.
