MS-3649

A 43-year-old female comes to the ENT clinic with a history of constant vertigo and right-sided deafness for the past year. She has no significant medical history. Upon conducting an audiogram, it is discovered that her right ear has reduced hearing to both bone and air conduction. During a cranial nerve exam, an absent corneal reflex is observed on the right side, and she has poor balance. Otoscopy of both ears is normal. What is the probable underlying pathology responsible for this patient’s symptoms and signs?
