MRI Differentiation Diagnosis of Occupying Lesions in Cerebellopontine Angle Area

摘要

Objective: To explore the value of magnetic resonance imaging (MRI) in diagnosis of occupying lesions in cerebellopontine angle area. Methods: MRI records of 78 patients with pathologically confirmed occupied lesions in cerebellopontine angle area were analyzed. Results: Of the 78 cases, 48 (61.5%) were unilateral acoustic neuroma, 5 (6.4%) were bilateral acoustic neuroma, 12 (15.4%) were meningioma, 4 (5.1%) were trigeminal neuroma, 3 (3.8%) were lipoma, 2 (2.6%) were melanoma, and 1 (1.3%) was medulloblastoma. According to the anatomic site, tumor lesion character, and MRI signal, the majority of cerebellopontine angle area tumors were diagnosed accurately. Conclusion: MRI plays an important role in diagnosis of occupying lesions in cerebellopontine angle area.
