Patient
male, 40 year(s)
 
 
  • Figure 1
    T1W SE axial slices before (1a-1b) and after (1c) contrast enhancement
     

    There is thickening of the uvula, the right lateral and posterior walls of the oropharynx.

     
    Area of Interest: unknown; Imaging Technique: T1W SE axial slices before (1a-1b) and after (1c) contrast enhancement;

    There is a massive thickening of the tonsilar area and the right pillars of the soft palate. The tumour shows a homogeneous, intermediate signal.

     
    Area of Interest: unknown; Imaging Technique: T1W SE axial slices before (1a-1b) and after (1c) contrast enhancement;

    There is a strong, homogeneous enhancement after Gd injection. The limits of the lesion in the pharyngeal wall are more clearly shown. Note the crossing of the midline as the invasion of the anterior part of the...

    T2W FSE coronal images
     

    Note the well depicted invasion of the soft palate and uvula. However, oedema may contribute to the thickening and high signal in the tumour area. So the extent has to be compared with the T1W post contrast scans.

     
    Area of Interest: unknown; Imaging Technique: T2W FSE coronal images;

    This more anteriorly situated slice shows the invasion of the tongue muscles, the tumour crossing the amygdalo-glossus groove.
