Rare infiltrative primary hepatic angiosarcoma: A case report and review of literature

Figure 5 Magnetic resonance imaging of the patient with primary hepatic angiosarcoma four months after diagnosis. A: Axial T1-weighted image; B: Axial T2-weighted image; C: Diffusion-weighted imaging; D: Axial T1-weighted image in the portal venous phase; E: Axial T1-weighted image in the delayed phase; F: Coronal T1-weighted image in the delayed phase. A large mass with mixed T1-weighted signals and mixed T2-weighted signals was observed in the right lobe of the liver. Multiple nodules with long T1-weighted signals and long T2-weighted signals were also observed in the liver. The large mass in the right lobe of the liver showed peripheral enhancement with hemorrhage. The giant mass compressed some branches of the right branch of the portal vein and the inferior vena cava. The remaining nodules showed progressive enhancement in the delayed phase.
