Figure

  • Figure 1 Multimodality imaging in a 71-year-old male. Axial plane nonenhanced (A) and contrast enhanced (B) CT images revealed a poorly enhanced mass around the heart. Magnetic resonance imaging indicated a mass arising from the pericardium of the left ventricle, that appeared mildly hyperintense on T2-weighted images (C) and hyperintense on T2-weighted fat-saturated images (D). FDG positron emission tomography/CT revealed high FDG uptake within the mass (SUVmax: 13.77) (E), while no other abnormal uptakes were observed in the body (F).CT = computed tomography; FDG =18F-fluorodeoxyglucose; SUVmax = maximum standard unit value.
