  • Figure 1
    Ultrasound
     

    Transverse section epigastric region shows hypo-echoic mass.

     
    Area of Interest: Abdomen; Liver; Pancreas; Imaging Technique: Ultrasound; Procedure: Diagnostic procedure; Special Focus: Aneurysms; Embolism / Thrombosis;

    Color Doppler image of the porta hepatis show flow in the hepatic artery (thin arrow) and right hepatic vein (arrowhead). Complete thrombosis of the main portal vein (thick arrow)

     
    Area of Interest: Abdomen; Liver; Portal system / Hepatic veins; Imaging Technique: Ultrasound-Colour Doppler; Procedure: Diagnostic procedure; Special Focus: Aneurysms; Embolism / Thrombosis;

    Transverse non-enhanced CT image show a dilated spleno-mesenteric confluence (5.4cm) with spontaneously hyperdense thrombus

     
    Area of Interest: Abdomen; Liver; Portal system / Hepatic veins; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Aneurysms; Embolism / Thrombosis;

    Transverse image in porto-venous phase. The aneurysmal dilatation of the spleno-mesenteric confluence (arrowheads) anteriorly displaces the pancreatic head (thin arrow). Slight stranding of the peripancreatic fat...

     
    Area of Interest: Abdomen; Liver; Portal system / Hepatic veins; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Aneurysms; Embolism / Thrombosis;

    Coronal MIP image in porto-venous phase. Large thrombosed aneurysm of the spleno-mesenteric confluence (arrowheads) extending in the main portal trunk (thick arrow) and in the splenic vein (thin arrow).

     
    Area of Interest: Abdomen; Liver; Portal system / Hepatic veins; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Aneurysms; Embolism / Thrombosis;

    Coronal MIP image in porto-venous phase. Partially visible aneurysm of the spleno-mesenteric confluence (arrowheads) with thrombus extending in the superior mesenteric vein (thin arrow) where the junction between...

     
    Area of Interest: Abdomen; Liver; Portal system / Hepatic veins; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Aneurysms; Embolism / Thrombosis;

    This 3D VRT coronal image better depicts local anatomy surrounding the aneurysm (arrowheads). Density difference between thrombus and contrast in splenic vein is observerd (thin arrow).

Transverse image in porto-venous phase. The aneurysmal dilatation of the spleno-mesenteric confluence (arrowheads) anteriorly displaces the pancreatic head (thin arrow). Slight stranding of the peripancreatic fat planes is observed (thick arrow).
 
Coronal MIP image in porto-venous phase. Large thrombosed aneurysm of the spleno-mesenteric confluence (arrowheads) extending in the main portal trunk (thick arrow) and in the splenic vein (thin arrow).
 
Coronal MIP image in porto-venous phase. Partially visible aneurysm of the spleno-mesenteric confluence (arrowheads) with thrombus extending in the superior mesenteric vein (thin arrow) where the junction between contrast and thrombus is clearly defined.
 
This 3D VRT coronal image better depicts local anatomy surrounding the aneurysm (arrowheads). Density difference between thrombus and contrast in splenic vein is observerd (thin arrow).
