Patient
female, 59 year(s)
 
 
  • Figure 1
    En-plaque meningioma
     

    CT scan, soft tissue window, of the right middle cranial fossa shows right exophthalmos and hyperostosis of the sphenoid wing with a discernible soft tissue mass along the lateral wall of the orbit (arrowheads).

     
    Area of Interest: unknown; Imaging Technique: En-plaque meningioma;

    CT scan, bone window, shows hyperostosis with involvement of all three layers of the sphenoid bone.

     
    Area of Interest: unknown; Imaging Technique: En-plaque meningioma;
     
     
  • Figure 2
    Presumed en-plaque meningioma
     

    Unenhanced T1-weighted axial MR image showing hyperostotic bone (arrow) as well as an isointense soft tissue mass along the lateral wall of the orbit (arrowhead).

     
    Area of Interest: unknown; Imaging Technique: Presumed en-plaque meningioma;

    Fast spin echo T2-weighted axial MR scan showing hyperostotic bone with no discernible soft tissue mass.

     
    Area of Interest: unknown; Imaging Technique: Presumed en-plaque meningioma;

    Enhanced T1-weighted axial MR scan shows extra-axial abnormal enhancement (arrow). Note also abnormal enhancement along the lateral wall of the right orbit (arrowhead).

     
    Area of Interest: unknown; Imaging Technique: Presumed en-plaque meningioma;

    Enhanced T1-weighted coronal MR scan shows hyperostotic bone (arrow), en-plaque meningioma (large arrow) and orbital extension of this meningioma (arrowhead).
