A 45-year-old woman presents with a 2-year history of progressive right-sided sensorineural hearing loss and tinnitus. She reports imbalance but denies vertigo. Vital signs: BP 128/82, HR 76, RR 14, Temp 37°C, SpO2 98%. Neurologic examination reveals right-sided diminished hearing and positive Romberg sign. Brain MRI demonstrates a 2-cm enhancing mass at the right cerebellopontine angle arising from CN VIII. Audiometry confirms sensorineural hearing loss. Which diagnosis best explains these findings?

  1. A)Medulloblastoma
  2. B)Meningioma
  3. C)Vestibular schwannomaGABARITO
  4. D)Pituitary adenoma
  5. E)Glioblastoma
