title: [Magnetic resonance imaging diagnosis of occupied lesions in cerebellopontine angle area:a report of 78 cases].
abstract: OBJECTIVE
  It is difficult to diagnose cerebellopontine angle area tumor because of many sorts and origins of the tumor. This study was to explore magnetic resonance imaging (MRI) diagnosis of occupied 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 hemangioblastoma, 3 (3.8%) were lipoma, 2 (2.6%) were melanoma, 1 (1.3%) was medulloblastoma. According to the anatomic site, tumor lesion character, and MRI signal character, the majority of cerebellopontine angle area tumors were diagnosed accurately.
  
  
  CONCLUSIONS
  MRI plays an important role in diagnosis of occupied lesions in cerebellopontine angle area.
