Abstract

Objectives: To investigate some features of clinical and magnetic resonance imaging of vestibular schwanoma. Subjects and methods: A prospective, descriptive, cross-sectional study on 74 patients with unilateral vestibular schwannoma who were microsurgical treated in Viet-Duc hospital from October 2016 to March 2018. Results: Female (58,11%) was predominant than male (41.89%). The age mean was 50.41% ± 9.43 (year). The most symptoms were tinnitus, hearing loss, headache, and ataxia (83.7%; 82.43%; 68.91% and 37.83%, respectively). There was no significant difference between the tumor’s location on the right and left side (54.41 versus 45.59%). 81.08% of tumors were heterogenesis and tumor compressing the cerebellum (95.94%), widening the inner ear canal (86.48%). The average tumor size was 38.1± 7.1 mm. Conclusion: The most symptoms were tinnitus, hearing loss, headache, and ataxia (83.7%; 82.43%; 68.91% and 37.83%, respectively). The tumor’s location: on the right side (54.41%) and left side (45.59%). 81,08% of tumors were heterogenesis and tumor compressing the cerebellum (95.94%), widening the inner ear canal (86.48%).
