Imaging findings of the case. (A) Ultrasound showing a well-defined, mixed-echoic mass in the liver. (B) MRI showing a well-demarcated, lobulated mass measuring 52 mm × 51 mm × 45 mm in size in the right lobe. The lesion was hypointense on T1WI (C) and hyperintense on T2WI. The lesion showed hyperintensity on both (D) DWI and (E) ADC map, indicating no restricted diffusion. On enhanced MRI, it exhibited irregular, continuous rim-like enhancement in (F) the early arterial phase and continued to fill centripetally in (G) the portal venous and (H) equilibrium phases, with a persistent defect in the center. MRI, magnetic resonance imaging; T1WI, T1-weighted imaging; T2WI, T2-weighted imaging; DWI, diffusion-weighted imaging; ADC, apparent diffusion coefficient.

Figure 2
Pathology findings of the case. (A) The margin of the tumor appeared lobulated, but well-defined against the adjacent parenchyma (HE). (B) It was composed of anastomosing small-caliber capillaries, lined by a single layer of cuboidal or hobnail endothelial cells (HE; original magnification 400×). (C) Focal extramedullary hemopoiesis was observed in the tumor (HE; original magnification 400×). Immunohistochemistry results showed diffuse (D) CD31, (E) CD34, and (F) ERG staining in the tumor cells (original magnification 200×). HE, hematoxylin and eosin.
