Abstract
|
|
|
|
Dandy-Walker syndrome is congenital malformation characterized by cystic enlargement of the fourth ventricle and agenesis or hypogenesis of the cerebellar vermis. The major clinical symptoms of the disease are hydrocephalus, weakening of physical strenth and athletic abilities, macrocephaly, cerebellar disorders like ataxia, nystagmus and irritability, vomiting from IICP. The syndrome usually occurs in early infancy and is barely diagnosed in adult. A fifty six aged female patient whose chief complaints were dizziness with right nystagmus and right hearing disturbance visited our outpatient clinic and showed ninety three/fifty six dB in right pure tone audiometry. So we prescribed PO medication on the assumption that she had right sudden sensoryneural hearing loss with vertigo, however left nystagmus was seen in her physical examination after discharge. We present this case that she was diagnosed as Dandy-Walker syndrome in brain MRI after all.
