Figure 2. Patient No. 5. (a) B-mode ultrasound shows a small well-demarcated hypoechoic central hyperechoic splenic tumour (arrows). (b) Power-Doppler ultrasound shows a vascular tumour with marked diffuse intratumoral flow signals (arrows). (c) In the early arterial phase (15 s), contrast enhanced ultrasound (SonoVue®) shows a central contrast filling indicating the increased vascular lesion (arrow). (d) In the late parenchymal phase (4 min) contrast enhanced ultrasound (SonoVue®) shows a hypoechoic contrast enhancement of the tumour in comparison with the surrounding normal splenic tissue (arrow). (e) Contrast CT shows a hyperintense vascular splenic tumour (arrow).
