Write answer in between .Q:A 57-year-old woman comes to the physician because of a 6-month history of tinnitus and progressive hearing loss in the left ear. She has type 2 diabetes mellitus and Raynaud syndrome. Her current medications include metformin, nifedipine, and a multivitamin. She appears well. Vital signs are within normal limits. Physical examination shows no abnormalities. A vibrating tuning fork is placed on the left mastoid process. Immediately after the patient does not hear a tone, the tuning fork is held over the left ear and she reports hearing the tuning fork again. The same test is repeated on the right side and shows the same pattern. The vibration tuning fork is then placed on the middle of the forehead and the patient hears the sound louder in the right ear. Which of the following is the most likely diagnosis?? A: Meningioma, B: Presbycusis, C: Acoustic neuroma, D: Cerumen impaction, E: Ménière diseasen,  <response>: This is a clinical vignette describing a 57-year-old woman with a 6-month history of unilateral tinnitus and progressive hearing loss in the left ear. Key findings include:- Unilateral symptoms affecting only the left ear- Positive Rinne test tuning fork louder on mastoid than over ear indicating conductive hearing loss- Positive Weber test tuning fork louder in right ear indicating left-sided hearing loss- No other abnormalities on physical examBased on the unilateral symptoms and tuning fork exam findings, this points towards a lesion affecting the left auditory pathway. Acoustic neuroma vestibular schwannoma is a benign tumor that can cause these unilateral symptoms by compressing the vestibulocochlear nerve. Meningioma and presbycusis would not cause unilateral symptoms. Cerumen impaction may cause unilateral conductive loss but other findings do not fit. Ménière disease classically causes fluctuating sensorineural hearing loss associated with vertigo episodes, which is not described here.C: Acoustic neuroma
