Hypothyroidism masquerading as cerebellar ataxia
Cerebellar ataxia can be a rare possible presentation of autoimmune hypothyroidism. We report a case of a young 20 years old female, who presented with bilateral cerebellar ataxia without any other significant neurological features. In detail investigations, she was discovered to be a case of Hashimoto Thyroiditis with positive anti-thyroid peroxidase (TPOAb) antibody and low freeT4 and freeT3 levels. She improved dramatically with levothyroxine therapy and iv pulse methylprednisolone. Thus, hypothyroidism should be looked for as a reversible and treatable cause in all cases of bilateral cerebellar ataxia.
