| Popis: | Arnold-Chiari malformation is a rare congenital condition characterized by varying degrees of downward displacement of the cerebellar tonsils, inferior cerebellum or medulla through the foramen magnum. Diagnosis of Arnold-Chiari malformation is not difficult due to the characteristic primary position downbeat nystagmus and a variety of cerebellar signs. Recently using magnetic resonance imaging (MRI), diagnosis of Arnold-Chiari malformation is more easy, but the degree of neurological disorder in the cerebellum and brainstem are not clarified without neuro-otological examination. We analyzed the eye movement using electro-nystagmograph in two cases of Arnold-Chiari malformation (one case is 14 old female and the other case is 54 old female) and discussed the differences of neuro-functional disorder between two cases that can not be discriminated by MRI techniques only. |
