Abstract
Hashimoto encephalopathy (HE) is a neuropsychiatric syndrome associated with positive
thyroid antibodies (Ab). Its pathophysiology is still in debate and pediatric cases
are considered rare. We present a case of an 11-year-old girl with new-onset refractory
status epilepticus (NORSE) who presented a good initial response to corticosteroids
but then required a second line of treatment with mycophenolate. In children presenting
with NORSE of suspected autoimmune origin and no identification of autoimmune encephalitis
traditional Ab, HE must be considered.
