(a) Plain posteroanterior chest radiograph showing diffuse bilateral mid and lower lung zone consolidation. (b) Axial CT scan (lung window, slice thickness: 2 mm) showing scattered nodules (arrows) combined with multifocal consolidation, ground glass opacities, and septal wall thickening. Centrilobular nodules are also evident in the right lung (between arrow heads) and thought to represent aerogenous spread of tumor cells. (c) Diffuse bilateral multilobar consolidation (black arrows) with the right lower lobe showing a mixture of consolidation, cystic airspaces, and pseudocavitations (white arrows).

Radiological investigations showed a mixture of multilobar consolidation, peripheral ground glass opacities with septal thickening, and multiple pulmonary nodules (Figure 1).
(a) Mucinous adenocarcinoma with lepidic growth pattern (white arrows). Two foci of invasion are seen close to a vessel (black arrow) and around a bronchiole (arrow head). Mucin is present in the alveoli (H&E x20). (b) The photograph depicts lepidic pattern (black arrows). Invasion of the peribronchiolar tissue is also evident at the center (between white arrows) (H&E x100).
