Patient
male, 28 year(s)
 
 
  • Figure 1
    skull radiography on first evaluation

    Overgrowth of the right temporal cortex. Note the radiolucent lesion of the squamous portion of the right temporal bone. Note also the areas of increased attenuation of the right mastoid and petrous apex.

     
    Area of Interest: unknown; Imaging Technique: skull radiography on first evaluation;
     
     
  • Figure 2
    skull, lateral view

    Ovoid radiolucent lesion surrounded by condensation of the squamous portion of the right temporal bone.

     
    Area of Interest: unknown; Imaging Technique: skull, lateral view;
     
     
  • Figure 3
    spiral CT scan,coronal section.

    Typical ground glass appearance in a widened diploic space of the temporal bone. Thinned but non ruptured cortex.

     
    Area of Interest: unknown; Imaging Technique: spiral CT scan,coronal section.;
     
     
  • Figure 4
    spiral CT scan,coronal section.

    Fibrous dysplasia of the right temporal bone : lytic lesion of the squamous portion of the right temporal bone. In periphery, CT shows thickening of both inner and outer tables.

     
    Area of Interest: unknown; Imaging Technique: spiral CT scan,coronal section.;
     
     
  • Figure 5
    spiral CT scan,axial section, bony windowing.

    Mixture of dense and radiolucent areas of fibrosis (pagetoid lesion). Lesion reached the right greater wing of the sphenoid bone. It reduced the size of the temporal fossa but did not invade it.

     
    Area of Interest: unknown; Imaging Technique: spiral CT scan,axial section, bony windowing.;
     
     
  • Figure 6
    spiral CT scan,coronal section

    Swelling of the right temporal muscle anterior to the temporo mandibular joint causing trismus.
