CTICasesMultifocal Adenocarcinoma with Tracheal Invasion

Imaging findings
In the superior segment of the left lower lobe, a subsolid lesion with pseudo cavitation and adjacent visceral retraction is seen, typical for adenocarcinoma. Multifocal ground-glass nodular opacities are present throughout the remainder of the lungs, with some solid nodules in the right and left upper lobes. A tracheal nodule near the carina, extending to the right mainstem bronchus, represents invasion of a large metastatic lymph node, with discontinuity of the tracheal cartilage.
Key takeaways
This case presents multifocal adenocarcinoma within the lungs, with one of the invasive lesions leading to nodal metastasis that then invaded the trachea. The patient experienced hemoptysis, and biopsy confirmed invasive adenocarcinoma. This is an unusual and aggressive appearance of adenocarcinoma with tracheal involvement.
