Figure 1 Color Doppler sonography of the portal vein aneurysm showing increased blood flow in the LPV and turbulence (arrow) at the distal portion of the aneurysmal sac.

Figure 2 PW Doppler sonography of the portal vein aneurysm showing a high speed blood flow at 1. 31 m/s in the aneurysm.

Figure 3 Contrast-enhanced CT showing a LPV density of 220. 6 Hu and an abdominal aorta density of 226.2 Hu at artery phase (A), a LPV density of 159.7 Hu and an abdominal aorta density of 168.0 Hu at portal venous phase (B), and CT of coronal section (C) and sagittal section (D) showing the direct shunt of APF.
