CTICasesInvasive mucinous adenocarcinoma
Imaging findings
Chest CT shows multiple bilateral, cavitating pulmonary nodules of varying sizes with irregular wall thickness, along with a large consolidative mass in the right lower lobe showing desmoplastic distortion of the adjacent oblique fissure and internal patent but distorted bronchi.
Key takeaways
Invasive mucinous adenocarcinoma of the lung can present as multifocal, cavitating nodules or consolidations, mimicking granulomatosis with polyangiitis or infection. Key differentiating features include desmoplastic pleural retraction and distortion of airways traversing the tumor.
