Intracranial extra-axial cavernous angiomas are rare lesions. We report a rare case of extra-axial cavernous angioma in the cerebellopontine angle (CPA) in a 50-year-old male, who presented with lower cranial nerve palsy and gait ataxia. Computed tomography (CT) scan of the brain showed a hyperdense lesion in the left cerebellopontine angle. The lesion was totally excised by the retrosigmoid approach and a pathological examination confirmed the lesion to be a cavernous angioma. Following surgery, the lower cranial nerve palsy recovered significantly.
颅内轴外海绵状血管瘤是罕见的病变。我们报告一例罕见的50岁男性小脑脑桥角（CPA）轴外海绵状血管瘤病例，该患者表现为低位颅神经麻痹和步态共济失调。脑部计算机断层扫描（CT）显示左侧小脑脑桥角有一个高密度病变。通过乙状窦后入路将病变完全切除，病理检查证实该病变为海绵状血管瘤。手术后，低位颅神经麻痹明显恢复。
