  • Figure 1
    CT
     

    CT shows a well-defined and pedunculated solid mass based at the tongue base. This mass shows low density on pre-contrast CT.

     
    Area of Interest: Ear / Nose / Throat; Imaging Technique: CT; Procedure: Contrast agent-intravenous; Special Focus: Neoplasia;

    The mass shows strong enhancement after contrast administration with anterior extension to the foramen caecum (arrow). There are eccentric, less enhancing portions in the left posterolateral aspect of the mass...

  • Figure 2
    MR
     

    On MRI, the mass shows high signal intensity on T2-weighted image.

     
    Area of Interest: Ear / Nose / Throat; Imaging Technique: MR; Procedure: Contrast agent-intravenous; Special Focus: Neoplasia;

    The sagittal T1-weighted image shows intermediate signal intensity of the mass, which extends to the foramen caecum (arrow).

     
    Area of Interest: Ear / Nose / Throat; Imaging Technique: MR; Procedure: Contrast agent-intravenous; Special Focus: Neoplasia;

    After administration of contrast, the mass homogeneously enhanced, except for an eccentric less enhancing area at the left lateral aspect of the mass (arrow head).

     
    Area of Interest: Ear / Nose / Throat; Imaging Technique: MR; Procedure: Contrast agent-intravenous; Special Focus: Neoplasia;
     
     
  • Figure 3
    PET-CT

    There is a strong uptake in the midline of the tongue base without evidence of distant metastases on PET CT.
