CALR and Graves disease: We considered the diagnosis of autoimmune cerebellar ataxia possible in this case for the following reasons: immune therapy was effective; anti-gliadin antibody, anti-thyroid antibody and anti-SS-A antibody that are suggested to be related to autoimmune cerebellar ataxia were present; the patient's history of Basedow's disease; and the definite diagnosis of Sjögren's syndrome on autopsy.
