Patient
female, 40 year(s)
 
 
  • Figure 1
    Coronal contrast enhanced MRI
     

    An enhancing extra-axial mass is seen in the left anterior cranial fossa. This is associated with an abnormally and asymmetrically dilated left frontal sinus.

     
    Area of Interest: Neuroradiology brain;

    The left frontal sinus is asymmetrically dilated. Note the normal-appearing left maxillary sinus.

     
    Area of Interest: Neuroradiology brain;
     
     
  • Figure 2
    Sagittal MRI
     

    Precontrast images show convex contour of the visualised left frontal sinus.

     
    Area of Interest: Neuroradiology brain;

    The inward bulging left frontal sinus is associated with an enhancing extra-axial intracranial mass lesion.

     
    Area of Interest: Neuroradiology brain;
     
     
  • Figure 3
    Axial T2-weighted MRI

    The left frontal sinus is asymmetrically enlarged. It is bulging and shows convex margins towards the mass.
