Patient
male, 48 year(s)
 
 
  • Figure 1
    Level of oropharynx

    Large, inhomogeneously enhancing soft tissue mass centered on the left parapharyngeal space, displacing and narrowing the oropharyngeal lumen. No fat plane is seen between the mass lesion and the left parotid gland....

     
    Area of Interest: unknown; Imaging Technique: Level of oropharynx;
     
     
  • Figure 2
    Level inferior to fig. 1.

    The lesion appears partly necrotic. Slight deformation of the left mandibular ramus is seen.

     
    Area of Interest: unknown; Imaging Technique: Level inferior to fig. 1.;
     
     
  • Figure 3
    Level inferior to fig. 2.

    Apart from narrowing of the oropharyngeal lumen, important compression of the tongue base is seen.

     
    Area of Interest: unknown; Imaging Technique: Level inferior to fig. 2.;
     
     
  • Figure 4
    Level inferior to fig. 3.

    The lesion can not be delineated from the left submandibular salivary gland (arrow). Normal heterolateral submandibular salivary gland (star).

     
    Area of Interest: unknown; Imaging Technique: Level inferior to fig. 3.;
     
     
  • Figure 5
    Level inferior to fig.4.

    Enlargement and increased enhancement of the left submandibular salivary gland. Thickening of the lateral wall of the vallecula and hypopharynx on the left side (arrows).

     
    Area of Interest: unknown; Imaging Technique: Level inferior to fig.4.;
     
     
  • Figure 6
    Level of nasopharynx.

    Also at this level the parapharyngeal space is obliterated, with infiltration of the surrounding structures. Note erosion of the left pterygoid process (arrow). Normal heterolateral parapharyngeal space (star).
