A 64 year old man presents with ipsilateral vertigo, tinnitus and left sided hearing loss. Exam: Renne test +ve and Weber’s lateralizes to the right ear. What is the most appropriate investigation?

The key is B. MRI brain. [Rinne positive, so it is not conductive deafness. Again we know if weber

lateralize to deaf ear it is conductive and lateralized away from deaf ear then it is sensoryneural. So here

there is sensoryneural hearing loss in left ear. So the most appropriate investigation is MRI brain. Why

not CT? As auditory involvement including acoustic neuroma is better visualized by MRI].
