Abstract
Hashimoto's encephalopathy is an anti-thyroid antibody-positive autoimmune encephalopathy. We herein report the case of a 13-year-old male patient with subacute vertigo, muscle weakness in the extremities and gait disturbance who was diagnosed with Hashimoto's encephalopathy. He showed no severe impairment of consciousness and no seizures, and there were no abnormalities on the brain MRI. However, epileptic spike and wave complexes were observed on an electroencephalogram, and a decline in blood flow was diffusely observed on brain SPECT (single photon emission computed tomography). His thyroid function was normal, but he was positive for anti-thyroid antibodies, such as anti-TPO (thyroid peroxidase) antibodies. He was also positive for serum anti-NAE (NH2-terminal alpha-enolase) antibodies. Systemic corticosteroid therapy and high-dose intravenous immunoglobulin therapy were effective, greatly improving his quality of life.
