CTICasesAdenocarcinoma with Lymphangitic Spread Mimicking Radiation Fibrosis

Imaging findings
CT shows focal ground-glass opacity within a region, a central mass, septal thickening, and bronchiectasis. The appearance has been long-standing.
Key takeaways
This case serves as a mimic of post-radiation pneumonitis and fibrosis. The persistence of the appearance for much longer than the typical time course for radiation pneumonitis suggests an alternative diagnosis. The findings represent adenocarcinoma with a desmoplastic response causing bronchodilatation and likely lymphangitic spread, in a patient with no history of radiotherapy.
