³Şişli Hamidiye Etfal Eğitim ve Araştırma Hastanesi, Patoloji Kliniği, Şişli, İstanbul, Türkiye Intracranial schwannomas account for 8-10 % of all intracranial tumors. Although acoustic neuromas are called by different names such as vestibular schwannoma (VS), VIIIth nerve schwannoma and peripheral glioma, acoustic neuroma is the most frequently used one. They account for 75-90% of cerebellopontine angle masses, being the most common type. There have been some classifications using tumor size, clinical symptoms and whether the tumor has an intracanalicular component. The mean time between the start of hearing loss and the diagnosis is reported to be 3.5-4 years. Treatment planning depends on various factors such as the patient’s age, neurological state and tumor size. Treatment options may be listed as observation, surgery and radiosurgery. Observation is an acceptable option, especially for the elderly group of patients with small and medium sized tumors and for mildly symptomatic patients. Follow-up of acoustic neuromas should be decided with physician-patient cooperation. If treatment is required, treatment options for acoustic neuromas are surgery and stereotactic radiosurgery (SRC).
