A man presents with muffled hearing and feeling of pressure in ear with tinnitus and vertigo. He also complains of double vision when looking to the right. What is the most appropriate dx?

The key is B. Acoustic neuroma. [An acoustic neuroma (vestibular schwannoma) is a benign tumor

that develops on the vestibular and hearing, or auditory (cochlear) nerves leading from patient’s inner

ear to the brain. The pressure on the nerve from the tumor may cause hearing loss and imbalance,

feeling of pressure in ear with tinnitus and vertigo. Involvement of other cranial nerves may occur, as

here right abducent nerve (double vision when looking to the right)].
