There is a lytic process in the 6th lt rib. Increased opacity in the hilar region, widening of mediastinum with trachea deviation ventrally and laterally towards the right ,due to enlarged LN. Pulmonary nodules.

Primary rib tumor with mets to LN and lung?

I disagree with the diagnosis of pulmonary neoplasia. On the VD there is clear irregular lysis of the 6th left rib with a faint opacity centered to it and a broad based directed to the lateral aspect. The left 7th rib is pushed caudally and closer to the 8th because of the mass effect caused by the lesion on the 6th rib. On the lateral view there is indeed an increased opacity caudodorsal to the heart base BUT NO mass effect is seen and this opacity does not silhouette with the lobar vessels to the caudal lung lobes which I can still see so that this opacity is certainly not a large lung mass. There are indeed nodular opacities consistent with pulmonary metastasis. The diagnosis should be primary rib neoplasia such as chondrosarcoma or osteosarcoma with likely pulmonary metastases.
