  • Figure 1
    3D TOF (time-of-flight) MR angiography

    MR contrast-enhanced angiography shows the presence of an aneurysmal dilatation at V2 level of the left vertebral artery (black arrow).

     
    Area of Interest: unknown; Imaging Technique: 3D TOF (time-of-flight) MR angiography;
     
     
  • Figure 2
    T1-weighted axial imaging of the neck

    Note the presence of the semi-lunar intramural haematoma at the left vertebral artery level (white arrow).

     
    Area of Interest: unknown; Imaging Technique: T1-weighted axial imaging of the neck;
     
     
  • Figure 3
    T2-weighted axial imaging of the neck

    The presence of the previously documented left vertebral artery semi-lunar haematoma is also easily seen on T2-weighted axial images (white arrow).
