    There is an intermediate signal tumour on the vestibular side of the left gingival groove. Note that there is a lateral extension towards the left jugal tissues. Mucosal thickening is seen in the left maxillary...

    Relationships between tumour and the wall of the maxillary sinus is not clearly defined on these low resolution images(<256², unfiltered).

    In this more posterior slice, see the large infiltration of the masticator space.

    Same comments as 1c. Note that postoperative changes are also visible on these slices, with a skin retraction in the scar areas.

    This shows the high signal of the mucosal thickening of the maxillary sinus, the low signal of the tumour itself.

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

    Note a higher signal in the peritumoral, oedematous areas. There is a lower signal tissue in the left maxillary sinus on this slice.

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

    Note the higher signal of the masticator muscles, this is one of the changes related to the denervation state accompanying the involvement of the inferior maxillary nerve (V3).

  • Figure 3
    Post Gd T1W coronal images, low resolution (< 256²)
     

    There is a frank, homogeneous enhancement of the tumour. Note a suspicion of disruption of the lateral wall of the sinus.

     
    Area of Interest: unknown; Imaging Technique: Post Gd T1W coronal images, low resolution (<256²,;

    There is no appearance of skull base or cavernous sinus involvement

    Note that the lamellar bone of the outer wall of the maxillary sinus is now well depicted.
