  • Figure 1
    MDCT axial images at the maxillary alveolar ridge level
     

    (A) Non-contrast image. Well-defined, hypodense mass centered on the right lateral wall of the oropharynx, crossing the midline with central calcific foci.

     
    Area of Interest: Head and neck; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Neoplasia;

    (B) Arterial phase. Lesion confined to the pharyngeal mucosal space bordered by medial pterygoid muscle. Minor enhancement (B, C) without bone erosion.

     
    Area of Interest: Head and neck; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Neoplasia;

    (C) Venous phase. Lesion confined to the pharyngeal mucosal space bordered by medial pterygoid muscle. Minor enhancement (B, C) without bone erosion.

     
    Area of Interest: Head and neck; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Neoplasia;
     
     
  • Figure 2
    MDCT axial images at mid-oropharyx level
     

    (A) Non-contrast image. The right-sided oropharyngeal mass shows heterogeneous hypodensity. Effacement of the right parapharyngeal space and contralateral deviation of the airway with narrowing.

     
    Area of Interest: Head and neck; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Neoplasia;

    (B) Arterial phase. Heterogeneous minor post-contrast enhancement. Effacement of the right parapharyngeal space, and narrowing of the airway with contralateral deviation.

     
    Area of Interest: Head and neck; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Neoplasia;

    (C) Venous phase. Heterogeneous minor enhancement and peripheral wall thickening/ pseudocapsule. No signs of bone or dental erosion.

     
    Area of Interest: Head and neck; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Neoplasia;
     
     
  • Figure 3
    MDCT axial images at the inferior oropharygeal level
     

    (A) Non-contrast image. Right-sided oropharyngeal mass crossing the midline, bordered by medial pterygoid and the angle of the mandible. Partial obliteration of the right parapharyngeal space.

     
    Area of Interest: Head and neck; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Neoplasia;

    (B) Arterial phase. Right-sided hypodense calcified oropharyngeal mass crossing the midline, protruding up to the retromolar trigone. Partial obliteration of the right parapharyngeal space.

     
    Area of Interest: Head and neck; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Neoplasia;

    (C) Venous phase. Poorly enhancing lesion with partial obliteration of the right parapharyngeal space.
