The diagnosis of spinocerebellar degeneration has been based on neurological, neuro-otological and radiological findings. CT scan and MRI can demonstrate atrophy of the cerebellum and/or pons on a two-dimensional plane. In this paper, three-dimensional evaluation by volumetry of the cerebellum and brain stem from MRI in 4 patients with spinocerebellar degeneration and 2 normal subjects was reported. MR images of the cerebellum and/or brain stem were put into a personal computer (Macintosh 7600/200), reconstructed three-dimensionally. Volume of the cerebellum or brain stem was calculated using commercial software (Vox Blast, Vay Tec Inc).<BR>In normal subjects, measured volume of the cerebellum was around 90 ml and that of the brain stem 17 ml. In patients with spinocerebellar degeneration, 2 patients with the cerebellar type showed reduced volume of the cerebellum with normal volume of the brain stem, while 2 other patients with the spinocerebellar type showed reduced volume in both the cerebellum and the brain stem.<BR>The authors considered that three-dimensional volumetry of the cerebellum and brain stem is useful for diagnosing spinocerebellar degeneration.
