Isolated horizontal canal hypofunction differentiating a canalith jam from an acute peripheral vestibular loss

摘要

Objectives: To describe a unique case of acute vertigo presenting with spontaneous horizontal nystagmus (SHN) and a clinical picture consistent with right acute peripheral vestibular loss (APVL) in which an isolated hypo function of a horizontal semicircular canal (HSC) permitted to detect a spontaneous canalith jam and treat the patient accordingly.
