Abstract：
We report a case of non-traumatic, multicanal benign paroxysmal positional vertigo (BPPV) in a premenopausal, osteopenic 35-year-old female with corresponding low bone mineral density. Dix-Hallpike and supine roll tests confirmed unilateral posterior canal (PC) BPPV from 2012-2014, and later, a rare presentation of multicanal BPPV with specifically ipsilateral horizontal canals (HC) and anterior canals (AC) affected in 2015. Heel scans displayed T-scores within the osteopenia range in 2012 until levels normalized one year later. Despite treatment with indicated canalith repositioning treatments (CRTs), symptoms continued to persist. Complete resolution of symptoms occurred in 2016, which is most likely due to self-treatment with daily 5000 IU vitamin D in 2015. This case emphasizes the rare presentation of unilateral single-canal BPPV to multi-canal BPPV, along with the importance of vitamin D treatment in preventing the recurrence of symptoms.
摘要：
我们报告了一个非创伤性病例,绝经前的多肛门良性阵发性位置性眩晕（BPPV），骨质疏松的35岁女性，相应的低骨密度。Dix-Hallpike和仰卧滚动试验证实了2012-2014年及以后的单侧后管（PC）BPPV，2015年罕见的多肛门BPPV，特别是同侧水平管（HC）和前管（AC）受累。脚跟扫描显示的T评分在2012年的骨质减少范围内，直到一年后水平恢复正常。尽管进行了指示的耳石重新定位治疗（CRT），症状持续存在。症状的完全缓解发生在2016年，这很可能是由于2015年每天5000IU维生素D的自我治疗。此病例强调了单侧单管BPPV到多管BPPV的罕见表现，以及维生素D治疗在预防症状复发方面的重要性。
