Splenic hamartoma mimicking angiosarcoma: A case report

Figure 2 Gadoxetic acid-enhanced liver magnetic resonance imaging and ¹⁸F-fluorodeoxyglucose positron emission tomography-computed tomography examination. The central portion of 8.2 cm × 6.2 cm splenic mass contained hemosiderosis (orange arrow) showing low signal intensity. In dynamic contrast enhanced magnetic resonance images, the splenic mass showed iso to high signal intensity. Contrast enhanced magnetic resonance images demonstrated the multiple hypervascular masses (arrowheads) in liver right hepatic lobe. Positron emission tomography-computed tomography demonstrated splenomegaly with mildly diffusely increased metabolic activity, raising suspicion of hematologic malignancy. A: T1-weighted image; B: T2-weighted image; C-E: In dynamic contrast enhanced magnetic resonance images; F: Positron emission tomography-computed tomography examination image.
