  • Figure 1
    Axial T1

    Axial T1 hypointense homogeneous mass in the right anterior PPS, displacing ICA ( blue dot) and IJV (red dot). Styloid process is also pointed out in violet.

     
    Area of Interest: Education; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Neoplasia;
     
     
  • Figure 2
    Coronal. T1 and T1 postgadolinium
     

    Coronal T1. Oval homogeneous mass well- deliniated in the anterior PPS displacing the ICA and IJV (carotid space) laterally

     
    Area of Interest: Head and neck; Imaging Technique: MR; Procedure: Imaging sequences; Special Focus: Neoplasia;

    Coronal T1. postgadolinium. Parapharyngeal mass with strong enhancement.

     
    Area of Interest: Head and neck; Imaging Technique: MR; Procedure: Imaging sequences; Special Focus: Neoplasia;
     
     
  • Figure 3
    Axial and sagital T2
     

    Axial T2. Moderately heterogeneous hyperintense mass. The mass is located anterior to the carotid space and medially to the deep parotid gland.

     
    Area of Interest: Head and neck; Imaging Technique: MR; Procedure: Imaging sequences; Special Focus: Neoplasia;

    Sagital T2. Hyperintense elongated mass in the parapharyngeal space.
