Abstract

Barany Society includes bilateral typical posterior semicircular canal benign paroxysmal positional vertigo (PSC-BPPV) in its classification of multicanal subtype. In the past decade, less-common and atypical subtypes of PSC-BPPV, like short-arm and non-ampullary arm posterior semicircular canalolithiasis, have emerged, requiring the conduct of conventional and auxiliary positional tests on both sides to uncover their bilaterality. Authors hereby report three atypical less-common subtypes of bilateral PSC-BPPV, discussing their clinicodemographic profiles, management by repositioning maneuvers and physical therapy, and follow up. Both Case 2 and Case 3 are precisely tri-canalolithiasis (bilateral ampullary arm posterior semicircular canalolithiasis with co-occurring right non-ampullary arm posterior semicircular canalolithiasis in Case 2 and bilateral short arm with co-occurring left ampullary arm posterior semicircular canalolithiasis in Case 3), which has not been reported previously in the literature. There has been only one previously reported case of bilateral non-ampullary arm semicircular canalolithiasis, and it is now observed in Case 1.

非典型双侧后半规管结石--一个病例系列。
摘要:巴拉尼学会将双侧典型后半规管良性阵发性位置性眩晕(PSC-BPPV)列入其多囊亚型分类中。近十年来,PSC-BPPV 出现了一些不太常见的非典型亚型,如短臂型和非髓臂型后半规管结石症,需要进行两侧常规和辅助体位测试才能发现其双侧性。作者在此报告了三种不典型、不太常见的双侧 PSC-BPPV 亚型,讨论了它们的临床人口学特征、复位手法和物理治疗方法以及随访情况。病例 2 和病例 3 恰好都是三管结石(病例 2 为双侧髓臂后半规管结石,同时伴有右侧非髓臂后半规管结石;病例 3 为双侧短臂后半规管结石,同时伴有左侧髓臂后半规管结石),这在以前的文献中从未报道过。此前仅有一例双侧非霰粒臂半规管结石的报道,目前在病例 1 中观察到了这种情况。

期刊介绍: The journal has a clinical foundation and has been utilized most by clinical neurologists for improving the practice of neurology. While the focus is on neurology in India, the journal publishes manuscripts of high value from all parts of the world. Journal publishes reviews of various types, original articles, short communications, interesting images and case reports. The journal respects the scientific submission of its authors and believes in following an expeditious double-blind peer review process and endeavors to complete the review process within scheduled time frame. A significant effort from the author and the journal perhaps enables to strike an equilibrium to meet the professional expectations of the peers in the world of scientific publication. AIAN believes in safeguarding the privacy rights of human subjects. In order to comply with it, the journal instructs all authors when uploading the manuscript to also add the ethical clearance (human/animals)/ informed consent of subject in the manuscript. This applies to the study/case report that involves animal/human subjects/human specimens e.g. extracted tooth part/soft tissue for biopsy/in vitro analysis.
