ABSTRACT
BACKGROUND & 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.CONCLUSION:
MRI plays an important role in diagnosis of occupied lesions in cerebellopontine angle area.
