Multiple cranial nerve dysfunction presenting as false localizing signs is rare. We report a 20-year-old woman who had concurrent trigeminal sensory disturbance, abducens, and peripheral facial nerve palsies in association with a contralateral acoustic neuroma. After surgery, the trigeminal nerve disturbance and the abducens nerve palsy completely recovered, but the peripheral facial nerve palsy persisted. The nature of tumor, the presence of brain stem distortion, the anatomic variation of posterior fossa, and the relationships of cranial nerves and nearby blood vessels, which are factors influencing the occurrence of false localizing, are briefly discussed.
表现为假性定位体征的多发性颅神经功能障碍较为罕见。我们报告一名20岁女性，她同时出现三叉神经感觉障碍、外展神经和周围性面神经麻痹，并伴有对侧听神经瘤。手术后，三叉神经障碍和外展神经麻痹完全恢复，但周围性面神经麻痹持续存在。本文简要讨论了影响假性定位发生的因素，包括肿瘤的性质、脑干变形的存在、后颅窝的解剖变异以及颅神经与附近血管的关系。
