Patient
male, 36 year(s)
 
 
  • Figure 1
    T1W SE axial before (1a) and after (1b) Gd IV
     

    Postoperative status with sequel of maxillectomy and metallic material inducing susceptibility artefacts. The masticator space is filled with an intermediate signal tissue.

     
    Area of Interest: unknown; Imaging Technique: T1W SE axial before (1a) and after (1b) Gd IV;

    There is a frank and homogeneous enhancement of the tumour in the masticator space.

  • Figure 2
    T1W SE coronal before contrast
     

    There is a filling of the right masticator space by a tissue of intermediate signal intensity

     
    Area of Interest: unknown; Imaging Technique: T1W SE coronal before contrast;

    Note the obtrusion of the fat spaces around the foramen ovale on the right side

    T1W SE coronal after Gd IV
     

    (Note: the grid-like artefacts are RF artefacts due to an external interference) There is a filling of the masticator space and the area of the right inferior orbital fissure by enhancing tumour tissue.

     
    Area of Interest: unknown; Imaging Technique: T1W SE coronal after Gd IV;

    The cavernous sinus and Gasser ganglion are widened and enhance. The Meckel's cave is obtruded on the right.

     
    Area of Interest: unknown; Imaging Technique: T1W SE coronal after Gd IV;

    There is a widening of the foramen ovale and tumour all around the way of the inferior maxillary nerve.
