FIGURE 2. Focal 18F-FDG uptake in 64-y-old woman who was being evaluated for staging of aggressive non-Hodgkin’s lymphoma. (A) From left to right, coronal, sagittal, and transaxial PET slices show focus of increased 18F-FDG uptake (arrows) in left pelvis. Coronal and sagittal PET images show additional areas of abnormal 18F-FDG uptake in mediastinum and left upper abdomen (open arrows), consistent with sites of active lymphoma. (B) Pelvic area of increased uptake (arrows) was localized by PET/CT (left panel) to sigmoid, as seen on corresponding CT image (right panel). Villous adenoma was diagnosed from biopsy sample taken during colonoscopy.
