Benign paroxysmal positional vertigo (BPPV) is diagnosed when vertigo and typical nystagmus are elicited by the positional maneuvers. Otherwise, the others unexplainable nystagmus beyond the typical form was called “atypical form” BPPV. The reports of atypical form in BPPV have been decreased according to expansion of knowledge or experience about various BPPV. Atypical BPPV include the switch or transitional, bilateral, and multi-canal type BPPV. Recently those complicated BPPV have been investigated by 3D video nystagmography and high resolution magnetic resonance image. Although we could not fully understand the etiology and pathophysiology of BPPV, These efforts to define the atypical BPPV should be helpful to grow up background knowledge of physician.
