What diagnosis to entertain?
The nodule has a likely endobronchial component and has relatively well-defined margins, a carcinoid tumour should be included as a possibility. Lung carcinoma is a less likely differential given the well-defined margins and low-risk background of the patient. Benign causes, although possible, are also felt less likely.
14 x 11 mm nodule in the right middle lobe lateral segment with smooth, lobular contours, no cavitation and no calcification. A branch of the middle lobe lateral segmental bronchus terminates in the nodule. A few other punctate lung nodules noted, up to 3mm, such as in the left lower lobe, nonspecific.
Borderline 8mm right hilar lymph node. No pleural or pericardial effusion.
