(a) Axial contrast-enhanced computed tomographic (CT) scan (lung window) depicts an upper left mediastinal mass (arrows) infiltrating the left upper lobe, which displays a “ground-glass opacity” (arrowhead). (b) Sagittal contrast-enhanced 2D reconstruction (soft tissue window) shows local tumoral extension (arrowheads) surrounding the aortic arch and origin of the left common carotid artery (asterisk). Both arteries are patent. (c) Coronal contrast-enhanced positron emission tomographic-CT scan reveals left upper lobe and mediastinal fludeoxyglucose (18F-FDG) uptake (asterisks). Hypermetabolic left supraclavicular lymph node (black arrow) and hypermetabolic pulmonary nodule in the right lower lobe (white arrow). Indirect signs of left recurrent laryngeal nerve palsy are present in terms of enlarged left laryngeal ventricle (white arrowhead) along with compensatory increased 18F-FDG uptake of the right vocal cord (black arrowhead)
