Horizontal semicircular canal variant of benign positional vertigo

Department of Neurology, UCLA School of Medicine, Center for the Health Sciences, Los Angeles, CA.

We report the clinical features and results of quantitative eye-movement testing in 13 patients with episodic positional vertigo and nonfatiguing direction-changing horizontal positional nystagmus (beating to the right with the head turned to the right and beating to the left with the head turned to the left). The benign history and lack of associated neurologic findings support a peripheral localization of the lesion. This syndrome probably represents a horizontal semicircular canal variant of benign positional vertigo. Free-floating debris in one horizontal canal may explain many of the clinical and oculographic findings.
