Figure 2
Contrast-enhanced ultrasonography (CEUS) of the lesion. (A) The lesion showed rapid and even hyper-enhancement in artery phase; (B) The center of the lesion began to subside in early portal venous phase and showed hypo-enhancement in the center; (C) The center of the lesion showed hypo-enhancement significantly in the portal venous phase; (D) In the later portal venous and delayed phase, the lesion showed hypo-enhancement in the center and iso-enhancement in the peripheral areas, compared with normal liver tissue."
Figure 3
(A) The lesion was located in segment IV, with a size of 4.6 × 3.4 cm. It was an oval lesion with low SI on T1WI; (B) Contrast enhanced MR image(provmist) showed fat wash-in and wash-out on arterial and venous phase; (C) The central necrotic area exhibited with less enhancement; (D) In hepatobiliary phase the lesion showed lower SI, compared with the normal parenchyma; (E) The oval lesion showed with high SI on T2WI; (F) The lesion showed high SI on DWI; (G) The lesion showed signal on ADC."
Figure 4
HE ×400. The tumor was composed of sarcomatoid cells arranged in a diffusely distributed pattern. The neoplastic cells displayed abundant eosinophilic cytoplasm, highly heterogenous nuclei with prominent nucleoli, and were occasionally binucleate.Malformed giant cells were present."
