This probably represents a primary bronchogenic carcinoma, what is your staging based on the imaging findings?
T2 - involves a main bronchus regardless of distance from the carina but without the involvement of the carina; N3 - suspected contralateral and left supraclavicular involved lymph nodes; MX - no definitive metastatic disease is seen in this study (needs further staging).
There is evidence of the partial collapse of the right lower lobe with surrounding mass in the right hilum surrounding the bronchus which appears attenuated and compressed with enlarged subcarinal node measuring 22 mm in short axis. The bronchial irregularity suggests tumour 15mm from the carina. There is also enlarged presumed hilar node measuring 22 mm in short axis. There are enlarged prevascular nodes measuring up to 18 mm in size extending towards the anterior mediastinum. There is also enlarged right lower paratracheal node measuring approximately 12 mm in short axis and mildly prominent right upper paratracheal nodes. Subcentimetre right axillary nodes are non-specific. A left supraclavicular node measuring 11 mm could represent N3 nodal involvement. No pleural or pericardial effusion. Adrenals are not completely included on the study. Fracture of T7 greater than 20 percent loss of anterior vertebral body height. No other suspicious bony lesions in the area encompassed by this scan.
