Presentation
Smoker with weight loss.
Patient Data
Frontal chest radiograph demonstrates left perihilar opacity. The opacity is seen on the lateral radiograph overlying the spine, further localizing it to the superior segment of the left lower lobe (LLL).
A large mass is seen in the superior segment of the left lower lobe. The mass demonstrates heterogeneous enhancement with probable central necrosis. Small mediastinal lymph nodes are seen as well. There is a background of moderate centrilobular and paraseptal emphysema.
Case Discussion
An opacity on a chest radiograph in a smoker should prompt further assessment and evaluation as those patients are at higher risk of lung malignancy.
Pathology: Adenocarcinoma, micropapillary predominant.
