Atypical PC-BPPV - Cupulolithiasis and Short-Arm Canalithiasis: A Retrospective Observational Study.
J Neurol Phys Ther
January 2025
College of Health Professions, Rosalind Franklin University, North Chicago, Illinois.
Background And Purpose: Atypical posterior canal (pc) benign paroxysmal positional vertigo (BPPV) may be caused by cupulolithiasis (cu), short arm canalithiasis (ca), or jam. The purpose of this study was to describe the clinical presentation and differential diagnosis of pc-BPPV-cu and short arm canalithiasis.
Methods: This retrospective observation study identified persons with atypical pc-BPPV based on history and findings from four positional tests.

Article Synopsis
- This study focuses on understanding positional nystagmus in patients with cupulolithiasis related to posterior semicircular canal-BPPV to enhance diagnostic accuracy.
- Researchers compared 128 cases of cupulolithiasis (PC-BPPV-cu) with 128 cases of canalolithiasis (PC-BPPV-ca), examining general data and nystagmus characteristics.
- Results revealed that PC-BPPV-cu patients often present in emergency departments, with the most common nystagmus being torsional-upbeat, easily triggered by specific head maneuvers, highlighting significant differences in nystagmus patterns between the two conditions.

Pharmacological therapies are used to control Benign paroxysmal positional vertigo (BPPV) symptoms for a brief period, discontinuing them usually results in recurrence. Canalolith repositioning maneuvers, including Epley, Semont, and Gans maneuvers, have been recommended for treating posterior canal BPPV with a high rate of success. A prospective, quasi-randomized study was carried out to compare the efficacy of Epley, Semont, and Gans maneuvers in the treatment of posterior canal BPPV and their durability.

Introduction: Benign paroxysmal positional vertigo (BPPV) is a vestibular disease characterized by brief positional vertigo. When examined, characteristic patterns of positional nystagmus (PN) are found with specific head position changes. Previous studies have shown a high prevalence of PN among vestibular healthy subjects.
