A male patient 67 years old presented with dyspnea and attacks of hemoptysis and proven histopathologically to have NSCLC. CT study reveals a malignant mass lesion involving the right lower lobe = 3 cm considered as T1 with a small 5 mm pulmonary nodule involving the right middle lobe at the para-cardiac region (a, b) and considered by CT to be non-specific nodule. A bone study by CT was negative. PET/CT study reveals positive FDG uptake detected inside the pulmonary nodule (white circle c) (T4), as well as positive active spots, noted affecting the thoracic bone namely the ribs, sternal body and the transverse process of the dorsal spine (M1c) (black circle) (e, f). The surgical staging of the patients by PET/CT changed from IIB to IVB
