The patient's family later confirmed that for one week prior, he had severe headaches, nausea and vomiting, slurred speech, and confusion. About few months previously, he had presented to another hospital with new onset seizures, was encephalopathic and was found to be hypothyroid. Extensive work-up had ruled out infectious, toxic, metabolic, malignant and paraneoplastic etiologies and Creutzfeldt–Jakob disease. His TSH levels were 8.08 IU/ml. TPOAb and TgAb were markedly elevated TPOAb >900IU/ml with TgAb >3000 IU/ml.
