摘　　要：目的观察和总结后半规管良性发作性位置性眩晕（PC-BPPV）的不典型临床表现,提高PCBPPV的检出率。方法回顾观察2014年1月~2015年1月在眩晕门诊确诊的57例PC-BPPV患者的不典型临床表现,分析并总结该组患者的性别、年龄分布、发病至就诊时间、不典型的临床表现形式。结果 PC-BPPV的不典型临床表现包括猝倒形式起病、非旋转性头晕、持续性头晕、头昏沉感、视物模糊、头脑不清晰感、头晕发作与头部活动无关、行走不稳定感、严重失衡、头紧缩感等。结论 PC-BPPV除经典表现外具有不典型的临床表现,其原因可能是病程长和双侧后半规管受累。对有不典型表现的患者常规进行Dix-Hallpike诱发试验可明确诊断,提高PC-BPPV的检出率。Objective To observe and summarize the atypical clinical manifestations of posterior canal benign paroxysmal positional vertigo （PC-BPPV） in order to increase the detection rate. Methods The atypical clinical manifestations of 57 patients diagnosed PC-BPPV were observed retrospectively. The gender, distribution of age, time from onset to present, forms of the atypical clinical manifestations were analyzed. Results The atypical clinical manifestations of PC-BPPV included sudden falling at acute onset, non-rotational dizziness, continous dizziness, heavy- headless, blurring vison, unclear sense of head, non-association between vertigo attack and movement of the head, unsteadness, serious imbalance and contractive sense of the head. Conclusions PC-BPPV may present atypical clinical manifestations because of long courses and bilateral posterior canal affected. Dix-Hallpike maneuver should be routinely performed to confirm the diagnosis of PC-BPPV and to increase the detection rate.
