case_images: Findings on chest radiography and CT. a Chest radiography shows a mass shadow in the right upper lung field. b, c Chest CT shows a 42-mm lobulated mass with ground-glass opacity in the right upper lobe. CT, computed tomography.

case_images: Chest radiography showed a mass shadow on the right upper lung field (Fig. 1a). Chest computed tomography (CT) with contrast showed a 42-mm lobulated mass and consolidation in the right upper lobe (Fig. 1b, c).
case_images: Findings on bronchial arteriography and chest CT before and after BAE. a Bronchial arteriography with microcatheter shows marked hypervascularity within the lung tumor. Chest CT before (b, c) and after (d, e) BAE shows reduction of the tumor size and the hypodense area in the tumor. CT, computed tomography; BAE, bronchial artery embolization.

case_images: Evaluation for the bleeding source by bronchial arteriography revealed marked hypervascularity within the lung tumor (Fig. 2a). One week after BAE, repeat chest CT showed reduction of the tumor size and the hypodense area in the tumor (Fig. 2b, c, d, e).
case_images: Pathologic findings of the right upper lobectomy specimen. a Grossly, cut sections of the lung show the tumor including a wide area of necrosis (arrows). b Microscopic examination of the entire tumor shows that only a small area is occupied by cancer cells (arrows). Hematoxylin and eosin stain, loupe view. c High magnification view shows the boundary between cancer cells (right) and necrotic tissues (left). Hematoxylin and eosin stain, x400.

case_images: Pathological findings revealed a wide area of necrosis with a small number of viable cancer cells in the tumor (Fig. 3a, b, c).
