The arrows point to what primary tumor in this 77-year-old male with lung cancer? What’s invaded? Is it cleanly resectable? Come up with your own answers, then check below the images to see my findings.

A Pancoast tumor (arrow) which crosses the cupola (fat pad at lung apex) of the lung, invades the brachial plexus and the vertebra. It is NOT resectable.
