Hashimoto's thyroiditis associated with recurrent transverse myelopathy.

A 55-year-old woman presented first episode of paraplegia at D6 level with a marked improvement of neurological signs, but relapse occurred five months later. Hashimoto's thyroiditis with euthyroidism was found. Long-term 9 months treatment with oral corticosteroids was applied. Also she was able to walk with help. Two years after the second palsy she developed a new paraplegia at D6 level with a severe residual deficit five months later in spite of oral corticosteroids. Thyroid antibodies remained positive. Devic's disease without optica neuritis associated with thyroiditis or spinal cord localisation of Hashimoto's encephalopathy was discussed.
