why would lymnodes be swollen in the chest after a right lung lobectomy?

Posted by Alisa

69 year old male presents with lung cancer. Has 2 lower right lung lobes removed. What was left of the upper right lung does not inflate and they go in again to remove the rest of the right lung.  It has been 3 months since left lung lobectomy and pet scan shows swolloen lymphnodes. Cancer was stage one tumor and was not present in the lymphnode biopsy.
