Imaging findings
CT showed significant mediastinal lymphadenopathy in prevascular, paratracheal, subcarinal, and AP window stations. There was a large consolidation in the right upper lobe, and extensive endobronchial spread of tumor (tumoroids) into the small airways throughout the lungs, notably not lymphatic carcinomatosis. Suspected contralateral endobronchial or hematogenous spread was also seen. PET scan revealed hypermetabolic activity corresponding to these lesions.
Key takeaways
Mucinous adenocarcinoma can present with aggressive features, including extensive endobronchial spread, which can be misdiagnosed as infection or other inflammatory processes. The combination of extensive consolidation, diffuse endobronchial opacities, significant lymphadenopathy, and high FDG avidity on PET is highly suggestive of advanced malignancy requiring prompt diagnosis.
