CTICasesBronchogenic Adenocarcinoma with Aerogenous Spread
Imaging findings
Serial CT scans over two years show a slowly growing right lower lobe part-solid nodule that progressed to extensive consolidative disease and aerogenous spread (lepidic nodules) in multiple lobes, confirmed as adenocarcinoma.
Key takeaways
Lepidic-predominant lung adenocarcinomas can spread via the airways (aerogenous spread of tumor). This manifests on CT as multiple nodules or consolidations in different lobes, mimicking multifocal bronchopneumonia or organizing pneumonia.
