ABSTRACT
The objective of our study was diagnostics and treatment of rare and complicated type of benign paroxysmal positional vertigo (BPPV) – lateral semicircular canal (LSC) cupulolithiasis. Treatment of this condition is more difficult than LSC canalolithiasis, it must be preceded by canal conversion. LSC canalolithiasis is characterized by low nystagmus fatigability, more intense vertigo and irritation nystagmus at the healthy side, less expressed vertigo at the diseased side according to Ewald’s law. The correct diagnostics and timely prompt positional treatment requires high qualification of a neurologist, patience and patient’s involvement making possible to avoid unnecessary prescriptions of expensive examination methods (MRI and CT) and neurologist’s consultations.
