Lateral Semicircular Canal Benign Paroxysmal Positional Vertigo diagnostic signs
I read with interest the article entitled Converting apo-geotropic into geotropic lateral canalolithiasis by head-pitching manoeuvre in the sitting position by Califano et al. 1. The Authors describe their experience in transforming the apogeotropic LSC BPPV (Lateral Semicircular Canal Benign Paroxysmal Positional Vertigo) into a geo-tropic one performing " a quick 60° forward exion and a slow ...

متن کاملPersistent positional nystagmus: a case of superior semicircular canal benign paroxysmal positional vertigo?
Involvement of the superior semicircular canal (SSC) in benign paroxysmal positional vertigo (BPPV) is rare. SSC BPPV is distinguished from the more common posterior semicircular canal (PSC) variant by the pattern of nystagmus triggered by the Dix-Hallpike position: down-beating torsional nystagmus in SSC BPPV versus up-beating torsional nystagmus in PSC BPPV. SSC BPPV may be readily treated at...
متن کاملAbout Nystagmus Transformation in a Case of Apogeotropic Lateral Semicircular Canal Benign Paroxysmal Positional Vertigo
THERE ARE TWO FORMS OF LATERAL SEMICIRCULAR CANAL BENIGN PAROXYSMAL POSITIONAL VERTIGO: geotropic and apogeotropic. When the pathophysiological mechanism of the apogeotropic form is that of canalolithiasis, we can observe a transformation from an apogeotropic nystagmus into a geotropic one. Usually, this phenomenon happens simultaneously on both sides, thus enabling us to observe a right-beatin...
متن کاملPseudo-Spontaneous Nystagmus in Lateral Semicircular Canal Benign Paroxysmal Positional Vertigo
OBJECTIVES Spontaneous nystagmus, which has been considered a typical sign of acute vestibulopathy, has recently been reported in benign paroxysmal positional vertigo involving the lateral semicircular canals (LC-BPPV) without unilateral vestibulopathy (pseudo-spontaneous nystagmus, PSN), but research about its clinical application is still limited. Here we investigate the frequency and charact...
