本文提出一种鉴别偏头痛性位置性眩晕（MPV）与水平管良性阵发性位置性眩晕（HC-BPPV）的方法。这种方法是必不可少的，因为这两种疾病之间的干预措施是不同的。本文介绍的病例研究的评价结果显示，持续性离焦性位置性眼震与MPV或HC-BPPV的壶腹结石变体一致。患者接受了松解术治疗，以从水平管中清除可能的耳锥碎片，从而提供进一步的诊断信息。HC-BPPV治疗后症状无变化。该病例随后被诊断为MPV，患者被转诊接受医疗干预。治疗成功22个月。因此，合并HC-BPPV治疗可能为MPV和HC-BPPV的壶腹结石变体的鉴别诊断提供有用的信息。
This article presents an approach to differentiation of migrainous positional vertigo (MPV) from horizontal canal benign paroxysmal positional vertigo (HC-BPPV). Such an approach is essential because of the difference in intervention between the two disorders in question. Results from evaluation of the case study presented here revealed a persistent ageotropic positional nystagmus consistent with MPV or a cupulolithiasis variant of HC-BPPV. The patient was treated with liberatory maneuvers to remove possible otoconial debris from the horizontal canal in an attempt, in turn, to provide further diagnostic information. There was no change in symptoms following treatment for HC-BPPV. This case was diagnosed subsequently as MPV, and the patient was referred for medical intervention. Treatment has been successful for 22 months. Incorporation of HC-BPPV treatment, therefore, may provide useful information in the differential diagnosis of MPV and the cupulolithiasis variant of HC-BPPV.
