  • Figure 1
    Axial T1 w image

    On axial T1 weighted image, a well defined lobulated predominantly hyperintense lesion is seen across the extra-axial right cerebellopontine cistern.

     
    Area of Interest: Neuroradiology brain; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Cysts;

    On the coronal T1 weighted fat suppressed image, the isointense to hyperintense extra axial lesion demonstrates well defined lobulated contour. Also note that the hyperintense areas within the lesion are not...

     
    Area of Interest: Neuroradiology brain; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Cysts;

    On the coronal T1 weighted fat suppressed image, the isointense to hyperintense extra-axial lesion shows extension into left CP angle cistern.

     
    Area of Interest: Neuroradiology brain; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Cysts;
     
     
  • Figure 4
    Axial T2 w diffusion image
     

    On axial T2 diffusion weighted image, the lesion demonstrates restricted diffusion.

     
    Area of Interest: Neuroradiology brain; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Cysts;

    On axial ADC image the lesion appears hypointense, confirming restricted diffusion.

    Axial T1 w contrast image

    On T1 weighted axial contrast enhanced image, the lesion does not demonstrate contrast enhancement. The hyperintense areas seen within the lesion on T1 weighted contrast image are also seen on precontrast T1 weighted...

On axial T1 weighted image, a well defined lobulated predominantly hyperintense lesion is seen across the extra-axial right cerebellopontine cistern.
 
On axial T1 weighted image, a well defined lobulated iso to predominantly hyperintense lesion located across the right cerebello-pontine cistern and crossing the midline to occupy the left cerebellopontine cistern through the prepontine cistern.
 
On the coronal T1 weighted fat suppressed image, the isointense to hyperintense extra axial lesion demonstrates well defined lobulated contour. Also note that the hyperintense areas within the lesion are not suppressed on this image.
 
On the coronal T1 weighted fat suppressed image, the isointense to hyperintense extra-axial lesion shows extension into left CP angle cistern.
 
On axial T2 diffusion weighted image, the lesion demonstrates restricted diffusion.
 
On axial ADC image the lesion appears hypointense, confirming restricted diffusion.
 
On T1 weighted axial contrast enhanced image, the lesion does not demonstrate contrast enhancement. The hyperintense areas seen within the lesion on T1 weighted contrast image are also seen on precontrast T1 weighted image.
