Abstract:

16 patients with hereditary cerebellar atrophy were admitted to our hospital in the past three years. Computed tomography scans were performed on all of the patients. The CT scans in 2 cases were within normal limits,and The other 14 cases all showed remarkable cerebellar atrophy. The main positive findings were as following:1. The sulci of the cerebellar hemispheres and/or the vermis widened and could be seen clearly.2. The fourth ventricle was enlarged.3. The cisterns around, the cerebellum and brain stem such as the quadrigeminal, superior cerebella, cerebellopontine angle and the prepontine cisterns were enlarged.4 In some cases the cerebral atrophy could be demonstrated. Thus, CT scan can provide the objective evidence for the diagnosis and differential diagnosis of the disease.
