  • Figure 1
    Doppler color and B-mode ultrasound scan

    Sagittal and axial plane imaging at the level of the left lower neck showed a well circumscribed mass with oval morphology and internal blood flow.

     
    Area of Interest: Head and neck; Imaging Technique: Ultrasound; Procedure: Education; Special Focus: Neoplasia;
     
     
  • Figure 2
    Axial T1-weighted pre and post contrast MRI

    Well-defined ovoid mass located between the left common carotid artery and internal jugular vein, with homogeneous intense enhancement, as intense as that of vascular structures. Post contrast sequence obtained with...

     
    Area of Interest: Head and neck; Imaging Technique: MR; Procedure: Education; Special Focus: Neoplasia;
     
     
  • Figure 3
    Subtraction axial MR image.

    Subtraction image confirms the presence of an enhancing mass

     
    Area of Interest: Head and neck; Imaging Technique: MR; Procedure: Education; Special Focus: Neoplasia;
     
     
  • Figure 4
    Axial T2-weighted MR image

    Axial T2- weighted image showing the mass as hyperintense compared to muscle with potential internal flow voids.

     
    Area of Interest: Head and neck; Imaging Technique: MR; Procedure: Education; Special Focus: Neoplasia;
     
     
  • Figure 5
    Axial diffusion-weighted MR image

    On axial diffusion-weighted imaging the lesion did not show restricted diffusion.

     
    Area of Interest: Head and neck; Imaging Technique: MR-Diffusion/Perfusion; Procedure: Education; Special Focus: Neoplasia;
