a NCCT axial image showed no significant abnormality at the operative bed, while b PET-CT fused image revealed 2 focal areas of abnormal FDG overactivity related to the anastomotic site (arrows) (SUVmax measures 4.4). c NCCT axial image showed right lobe segment VII hypodense focal lesion, while d PET-CT fused image confirmed right hepatic lobe FDG avid, hyper metabolically active focal lesion (SUVmax measures 14.0). e NCCT serial images showed rounded shape enlarged left external iliac lymph node compressing the adjacent segment of left ureter & subsequent hydroureter and hydronephrosis, while f Fused PET-CT images revealed and confirmed left external iliac avid metabolically hyperactive LN (SUVmax measures 13.0)
