For patients with lymph nodes measuring 16 mm on CT and a negative FDG-PET result a post-test probability for N2 disease of 21% was found, suggesting that these patients should be planned for mediastinoscopy prior to possible thoracotomy to prevent too many unnecessary thoracotomies in this subset. Two men with dyspnea, enlarged lymph nodes - Dx? Swollen nodes with a bacterial infection are usually over 1 inch (25 mm) across.
