a NCCT of the abdomen showing soft tissue density related to the operative bed inseparable from the left ilio-psoas muscle complex. b Fused PET-CT image revealed and confirmed operative bed FDG avid metabolically overactivity denoting recurrence, infiltrating the left ilio-psoas muscle (SUVmax measures 13). c NCCT of the abdomen showing thickened left peri-renal fascia. d Fused PET-CT image confirmed FDG avid metabolic overactivity (SUVmax measures 10). The arrow refers to left ureteric double-J catheter. e NCCT of the abdomen showing nodular soft tissue density at the left anterior abdominal wall (arrow). f Fused PET-CT image confirmed FDG avid metabolic overactivity (arrow) (SUVmax measures 9). g NCCT of the abdomen showing right hepatic lobe segment-IV ill-defined hypodense focal lesion ± 3.5 cm in diameter, h Fused PET–CT image confirmed right hepatic lobe segment-IV FDG avid hypermetabolic active focal lesion eliciting (SUVmax 12.5). i NCCT lung window axial image shows right para hilar speculated soft tissue density mass lesion ± 3 cm surrounded by reticular densities and atelectatic bands (arrow) j Fused PET –CT image confirmed right para-hilar FDG avid hypermetabolic active deposit (SUVmax measures 16.5) (arrow). k NCCT lung window axial image shows small peripheral nodule (+ 7 mm) at the right lower lung lobe (arrow), l Fused PET–CT image revealed FDG-avid small nodule of low grade activity at the left upper lung lobe (SUVmax measures 2.7) (arrow)
