title: Comparative study on computed tomography and neurotological findings in spinocerebellar degeneration.
abstract: The classification of SCD on the basis of the neurotological findings was with classification based on CT findings in 40 cass of SCD. The areas of pons, cerebellar hemisphere, vermis and posterior fossa on CT films were measured by craniometer, and were compared in order to estimate the degree of atrophy. From these assessments, patients were classified into 3 types as follows; (1) 14 cases of cerebellar type, (2) 9 cases of brain stem type and (3) 17 cases of combined type. The classification of SCD based on the neurotological findings including the findings of gaze test, positioning test, eye tracking test, OKN, and fixation suppression test of caloric nystagmus, was well correlated to the classification based on CT findings. From the results, neurotological examination was demonstrated to make a contribution to the estimation of lesions and types in SCD.
