Ultrasound Scan Findings:
At the porta hepatis of the liver, there were multiple tiny tortuous blood vessels around an abnormal-looking main portal vein which contained thrombus (Figure 1). These tiny vessels also demonstrated hepatopetal blood flow under color Doppler interrogation suggestive of formed collaterals secondary to an occluded portal vein. There was impaired visualization of the left and right intra-hepatic portal vein branches sonographically.
