Click (Figure 1) 10 year old male with portal venous pseudoaneurysm following blunt abdominal trauma. Initial coronal arterial-phase contrast enhanced CT (Siemens Somatom Sensation 4 slice scanner, 120 kV, 380mA, 65mls omnipaque contrast media) of the upper abdomen demonstrates a wedge shaped region of low attenuation within the right lobe of the liver consistent with large liver laceration. The portal vein is normal. Free fluid is seen below the right lobe of the liver.

Click (Figures 3 and 5) 10 year old male with portal venous pseudoaneurysm. 2 weeks following blunt abdominal trauma axial portal-venous contrast enhanced CT in the arterial phase (Siemens Somatom Sensation 4 slice scanner, 120 kV, 380mA, 65mls omnipaque contrast media) demonstrates avidly enhancing focus in proximity to portal vein consistent with pseudoaneurysm. The liver laceration is also demonstrated. There is high attenuation material within a distended gallbladder consistent with recent haemorrhage. Intraperitoneal fluid is seen within the abdomen surrounding the liver capsule and spleen.
