Figure 1: Post-contrast axial computed tomography scan (a) at the level of the internal auditory canal (IAC) demonstrates enhancing left CPA mass. Post-contrast T1-weighted image (b) at the same level demonstrates intensely enhancing left CPA mass, without any extension of enhancement into the left IAC. Axial T2-weighted (c) and fluid attenuated inversion recovery (FLAIR) (d) images demonstrate a mass adjacent to the left jugular foramen having both intra-osseous and perimedullary cistern component, which is slightly hyperintense on T2-weighted image (c) and hyperintense on FLAIR image (d). There are multiple flow-voids on the FLAIR image and fluid in the left mastoid as well as in the left middle ear cavity (d). Post-contrast T1-weighted coronal image (e) and axial image (f) shows a left jugular foramen lobulated mass and extending up to the left CPA cistern
