Two years after surgery, surveillance FDG-PET/CT revealed an avid mediastinal nodular lesion (SUV > 4, 5) located between the posterior wall of the left main stem bronchus and the descending thoracic aorta not clearly identifiable as a lymph node and close but not clearly along the staple line (Fig. 1).
Bronchoscopy findings showed localized irregularity of mucosa corresponding to chronic inflammation on bronchial biopsy specimen (HE stain, x100).
