==Background==
[[File:Blausen 0009 AcousticNeuroma.png|thumb|Acoustic neuroma schematic.]]
*As known as "acoustic neuroma"
*Schwann cell derived tumor of [[cranial nerve]] VIII
*Typically arise from vestibular division of CN VIII--> expands--> projects from internal auditory canal into cerebellopontine angle--> compresses CN VII and VIII
**Less commonly, can continue to enlarge and compress cerebellum, brain stem, and CN V, IX, and/or XII

==Clinical Features==
*[[Hearing loss]], sensorineural, slowly progressive or abrupt 
*[[Vertigo]]/dysequilibrium
*[[Tinnitus]], unilateral
*[[Otalgia]] or sensation of ear fullness/pressure
*[[Facial paralysis|Facial weakness]] or [[numbness]] if facial nerve involvement

==Differential Diagnosis==
{{Vertigo DDX}}

===Sensorineural [[hearing loss]]===
*[[Sudden Sensorineural Hearing Loss (SSHL)]]
*Infections: ([[Meningitis]], Viral cochleitis)
*[[Barotrauma]]
*[[Neck Trauma|Penetrating trauma]]
*[[Meniere Disease]]
*Autoimmune disease
*[[Multiple Sclerosis]]
*[[Stroke (Main)|Cerebrovascular ischemia]]
*Tumors ([[Acoustic neuroma]], Meningioma)
*Hereditary hearing loss
*Congenital [[viruses|viral infections]]
*Congenital malformations
*Presbycusis
*[[Thyrotoxicosis]]
*Ototoxic drugs: [[Aminoglycosides]], [[Erythromycin]], [[Tetracycline]], chemotherapeutic agents, high-dose [[aspirin]], phosphodiesterase-5 inhibitors (e.g. [[sildenafil]], [[antimalarial]] drugs, [[Cocaine]], [[Heavy Metals]]
*Otologic surgery
*Noise exposure

==Evaluation==
[[File:Akustikusneurinom Mrt.jpg|thumb|Vestibular schwannoma on MRI.]]
*[[Brain MRI]]
*Outpatient audiogram

==Management==
*Typically monitored without resection unless rapidly growing or bothersome symptoms

==Disposition==
*Discharge
