Imaging studies upon presentation and upper endoscopy. A–E Contrast-enhanced 18FDG PET-CT exhibited hepatomegaly (22 cm longitudinal axis) with multiple large FDG-avid liver masses, measuring up to 12 cm and SUV max of 13.5. A focus of FDG avidity in the gastric antrum had no structural correlate (red arrows), with an SUV max of 9.4. CT also showed mesenteric lymph nodes and small lung infiltrates. F Thyroid scan (99mTcO −4 ) with tendency to diffusely increased tracer uptake (radioiodine thyroid scan was not performed due to use of IV-iodinated contrast in the preceding two days). G Upper endoscopy showing a ~ 5 cm bleeding lesion in the greater stomach curvature body
