Figure 3. Patient No.10.(a) B-mode ultrasound shows two well-demarcated hypoechoic central hyperechoic splenic lesions. (b) Colour-Doppler ultrasound shows two vascular tumours with marked radial intratumoral flow signals in both lesions. (c) In the early arterial phase (11 s), contrast enhanced ultrasound shows a peripheral contrast enhancement of both tumours in comparison with the surrounding normal splenic tissue (arrows). (d) In the parenchymal phase (1 min), contrast enhanced ultrasound shows a complete filling of both lesions with an isoechoic enhancement of both tumours in comparison with the surrounding normal splenic tissue. (e) In the late parenchymal phase (3 min), contrast enhanced ultrasound shows a wash out phenomenon of both lesions with a hypoechoic enhancement of both tumours in comparison to the surrounding normal splenic tissue (arrows). (f) Contrast CT shows a hyperintense peripheral ring enhancement of the splenic tumour (arrow). (g) Contrast CT shows a complete filling of the splenic tumour (arrow).
