  • Figure 1
    A CT scan
     

    An axial post-contrast CT image showing an enhancing epidural left petrous apex collection.

     
    Area of Interest: unknown; Imaging Technique: CT scan;

    A coronal post-contrast CT scan showing an enhancing epidural left petrous apex collection with a downward extension to the superior pharyngeal mucosal space.

     
    Area of Interest: unknown; Imaging Technique: CT scan;

    An axial CT image ( bone window) showing the extensive destruction of the left petrous apex and soft tissue opacification of the ipsilateral tympanic cavity and mastoid antrum, with mastoidal sclerosis.

     
    Area of Interest: unknown; Imaging Technique: CT scan;
     
     
  • Figure 2
    MRI
     

    An axial T1-weighted image showing a hypointense left apex lesion (compared with the contralateral hyperintense petrous apex, which is due to the fat content of the bone marrow).

     
    Area of Interest: unknown; Imaging Technique: MRI;

    An axial T2-weighted image showing the left apex lesion to be hyperintense.

     
    Area of Interest: unknown; Imaging Technique: MRI;

    An axial volumetric post-contrast T1-weighted image demonstrating intense peripheral enhancement in the left petrous apex.
