Figure 2 Contrast enhanced computed tomography and ¹⁸F-fluorodeoxyglucose-positron emission tomography. A: Thickened peritoneum and mesentery with multiple nodules were positively enhanced by the contrast material; B: An umbilical hernia is also evident (arrow); C: A coronal image of ¹⁸F-fluorodeoxyglucose-positron emission tomography (FDG-PET) showed no localized areas of high accumulation of FDG, but mild accumulation of FDG was observed over the entire abdominal region.
