CTICasesPrimary Lung Adenocarcinoma with Diffuse Aerogenous Spread
Imaging findings
Chest CT demonstrates a large, primary lung mass in the lower lobe accompanied by widespread, bilateral centrilobular ground-glass nodules, confluent consolidations, and multiple ring-like cavitary nodules with thin walls resembling "cheerios."
Key takeaways
Primary lung adenocarcinoma, particularly the mucinous subtype, can present with extensive aerogenous spread of tumor, producing a radiographic pattern that closely mimics multifocal bronchopneumonia. Morphological findings typically include a combination of centrilobular nodules, consolidations, and cavitary "cheerios" caused by tumor cells lining the alveolar walls.
