    18F-FDG PET maximum-intensity-projection image (A) reveals few hot spots in paramedian plane of right upper abdominal region and in pelvic region. Transaxial (B and C) and sagittal (D and E) CT images (B and D) and PET/CECT images (C and E) of pelvis reveal 18F-FDG–avid (SUVmax, ∼21.7) long segmental asymmetric wall thickening (arrows) in sigmoid colon, with perilesional stranding and nodularity.

    Transaxial CT images (A and C) and PET/CECT images (B and D) of upper abdomen reveal 18F-FDG–avid filling defect in main portal vein (solid arrows; SUVmax, 18.3) and left portal vein (dashed arrows; SUVmax, 16.9).
