A CISS, and B T2 WI sequence showing thickening of the cisternal segment of the seventh-eighth nerve complex on the left side. The underlying right middle cerebellar peduncle shows T2 hyperintense signal. Fluid signal is noted replacing the normal mastoid air cells on the right suggestive of mastoiditis (red arrow). Inflammation is noted along the floor of the left orbit and sphenoid sinusitis. C T1 WI post-contrast axial sequence showing abnormal enhancement along the right cavernous sinus extending into the orbit
