Findings:
There is focal enhancement of the canalicular right facial-vestibulocochlear nerve complex in comparison to the left. There is an asymmetric enhancement of the right geniculate ganglion as well as the right tympanic and mastoid facial nerve.
There is an incidental left type II anterior inferior cerebellar artery( AICA) loop.
Multiple FLAIR hyperintense lesions in the supratentorial white matter, are in keeping with mild to moderate small vessel ischemia. The brain parenchyma is otherwise unremarkable. No diffusion restriction.
No intra- or extra-axial mass lesion or collection is identified. The ventricles and sulcal spaces are within normal limits. The midline structures are normal with no midline shift.
The orbits, paranasal sinuses and mastoid air cells are clear.
No bony abnormality is seen. The craniocervical junction is normal.
Conclusion:
Focal canalicular enhancement at the apex of the right internal auditory canal, likely representing a combined enhancement of the facial-vestibulocochlear nerve complex, in keeping with the clinical diagnosis of right-sided Ramsay Hunt syndrome with right-sided Bell’s palsy. No intracranial mass lesion.
