  • Figure 1
    Axial CT scan with intravenous contrast

    A large mass with well-defined margins arises from the posterolateral wall of the oropharynx. The mass shows heterogeneous, intense enchancement.

     
    Area of Interest: Head and neck; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Neoplasia;
     
     
  • Figure 2
    Coronal CT scan with intravenous contrast

    The tumour compresses the left parapharyngeal space and protrudes into the hypopharynx causing significant narrowing of the aerodigestive tract.

     
    Area of Interest: Head and neck; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Neoplasia;
     
     
  • Figure 3
    Axial T1W MRI

    On T1W imaging the lesion reveals relatively homogeneous signal intensity similar to that of muscle.

     
    Area of Interest: Head and neck; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Neoplasia;
     
     
  • Figure 4
    Coronal T2WI and axial STIR MRI images
     

    The mass displays heterogeneous hyperintensity with flow voids due to vessels. High signal represents areas of cystic necrosis.

  • Figure 5
    Coronal post-gadolinium T1W MRI

    The mass enhances avidly apart from necrotic areas. Note intact overlying mucosa.
