  • Figure 1
    Ultrasonography

    Ultrasonography revealed stenosis at the origin of the coeliac trunk (star) and a dilated and tortuous artery lying around the head of the pancreas (arrows).

     
    Area of Interest: Abdomen; Imaging Technique: Ultrasound-Power Doppler; Procedure: Arterial access; Special Focus: Arteriovenous malformations;
     
     
  • Figure 2
    MRCP

    MRCP showed the dilation of intra-hepatic bile duct and upper segment of the bile duct, associated with dilated and tortuous arterial collaterals of pancreaticoduodenal arcade.

     
    Area of Interest: Biliary Tract / Gallbladder; Imaging Technique: MR; Procedure: Education; Special Focus: Dilatation;
     
     
  • Figure 3
    Angio MRI

    AngioMRI demonstrated stenosis at the origin of the coeliac trunk.

     
    Area of Interest: Arteries / Aorta; Imaging Technique: MR-Angiography; Procedure: Arterial access; Special Focus: Arteriosclerosis;
     
     
  • Figure 4
    Abdominal MRI

    Coronal T2 sequence, showing dilated and tortuous arteries lying over the anterior surface of the head of the pancreas responsible of the obstruction of the lower common bile duct.

     
    Area of Interest: Abdomen; Imaging Technique: MR; Procedure: Complications; Special Focus: Arteriovenous malformations;
