Brainstem hemorrhage usually presented with acute multiple neurologic dysfunction, and the prognosis was poor. Rarely, it can manifest with audiovestibular symptoms only. Here, we report a case of brainstem hemorrhage involving the right middle cerebellar peduncle and dorsal lateral pons presented with constant nonpulsatile tinnitus and rotatory vertigo. We believed that rotatory nystagmus should be regarded as a central sign until proven otherwise even if the neurologic signs are subtle.
脑干出血通常表现为急性多发性神经功能障碍，预后较差。很少见的情况下，它也可能仅表现为听觉-前庭症状。在这里，我们报告了一例累及右侧小脑中脚和背外侧桥脑的脑干出血病例，表现为持续的非搏动性耳鸣和旋转性眩晕。我们认为，即使神经体征不明显，旋转性眼球震颤也应被视为一种中枢性体征，直到有其他证据证明。
