Figure 1 Multiple hepatic epithelioid hemangioendotheliomas in a 31 year female. A: Grayscale ultrasound showed a distinct hypoechoic focal liver lesion (FLL) (arrow); B: Multiple hypoechoic lesions (arrows) were also detected in this patient; C: Color Doppler imaging (CDFI) showed peripheral and intra-lesion color flow signals; D: The resistive index (RI) of color flow was 0.70.

Figure 2 Contrast-enhanced ultrasound feature of hepaticepithelioid hemangioendothelioma in a 31 year female. A: Rim-like enhancement. In arterial phase (16 s after injection of SonoVue), peripheral rim-like enhancement was demonstrated; B: In peak enhancement (24 s after injection of SonoVue), the degree of the rim-like enhancement was equivalent to the liver parenchyma; C: In portal venous phase (45 s after injection of SonoVue), the lesion washed out quickly and showed hypoenhancement; D: In late phase (65 s after injection of SonoVue), the lesion remained hypoenhanced with central unenhanced area.

Figure 3 Contrast-enhanced ultrasound feature of hepatic epithelioid hemangioendothelioma in a 25 year female. A: Heterogeneous enhancement pattern. In the arterial phase (16 s after injection of SonoVue), the lesion showed heterogeneous enhancement; B: The enhancement gradually decreased (22 s after injection of SonoVue); C: In the portal venous phase (40 s after injection of SonoVue), the lesion washed out fast than the liver parenchyma and showed hypoenhancement. D: In the late phase (165 s after injection of SonoVue), the lesion remained hypoenhanced.

A: Grayscale ultrasound showed a hypoechoic focal liver lesions (FLL); B: In the arterial phase the lesion showed heterogeneous enhancement (22 s after injection of SonoVue); C: In the portal venous phase (53 s after injection of SonoVue), the lesion washed out fast and showed hypoenhancement.
