The left petrous apex shows an intermediate to low signal on T1, high signal on T2, FLAIR fat sat, and DWI with peripheral irregular enhancement. Associated middle ear fluid and partial opacification of the mastoid air cells.
Thickening of the dura of the ipsilateral Meckel's cave and cavernous sinus.
Case Discussion
The MRI features are most consistent with petrous apicitis resulting in Gradenigo syndrome.
Petrous apicitis, also known as apical petrositis, is an infection of the petrous apex of the petrous temporal bone.
