He was referred for further evaluation of the lesions. a Axial CT image of the right lung base showed solitary right middle lung lobe medial segment sub pleural pulmonary nodule with speculated outline and measures 1.3 cm in diameter (red arrow). b Axial fused PET/CT image revealed avid FDG uptake by the solitary right lung nodule with SUVmax 8.6 (red arrow). c, d Axial fused PET/CT image of the liver revealed no abnormal FDG uptake by hepatic bi-lobar hypodense focal lesions at segments II and VIII (white arrows) in keeping with benign etiology. e Whole body MIP PET image revealed avid FDG uptake by the solitary right lung nodule (red arrow) with no abnormal uptake elsewhere
