A chest radiograph revealed bilateral nonhomogeneous opacities, predominantly in the middle third of the right lung (Figure 1).
HRCT scans at four levels (a)-(d) demonstrate confluent airspace nodules and areas of consolidation in both lungs, with signs of architectural distortion that are characterized by bronchial dilatations within the lesions (white arrowheads in (a)) and fissure distortion with loss of the regularity (white small arrows in (d)).

The high-resolution computed tomography (HRCT) demonstrated confluent airspace nodules, forming areas of consolidation in both lungs, with signs of architectural distortion (Figure 2).
(a)-(c): Photomicrographs demonstrate active young fibroblast proliferation (fibrosis) and tumor cells that are entrapped within the central desmoplasia. (d): Photomicrograph shows neoplastic cells spreading along alveolar septa (lepidic growth) with preservation of the alveolar architecture (hematoxylin-eosin stain).
