Description

We reported a 61-year-old man who had developed acute cerebellar ataxia in the trunk and the lower limbs. His chemical blood analysis showed very mild hypothyroidism and the presence of serum anti-thyroid peroxidase (TPO) antibody and anti-NH2 terminal of alpha-enolase (NAE) antibody. While cerebellar atrophy was not evident on magnetic resonance imaging (MRI) of the brain, 99mTc-ECD SPECT using the easy Z-score imaging system (e-ZIS) showed decreased regional cerebral blood flow (rCBF) in the vermis of cerebellum. His cerebellar ataxia improved spontaneously within three weeks. The present case is very rare and suggests that anti-NAE autoantibody may be associated with actue cerebellar ataxia.<br>
