Dear Sir,

Hashimoto’s encephalopathy (HE) is a controversial autoimmune condition of the central nervous system (CNS) characterized by focal and/or diffuse symptoms concomitant with raised levels of anti-thyroid antibodies, in particular anti-thyroperoxidase (TPO) and/or anti-thyroglobulin (TG) antibodies [1]. Hereby, we provide the full clinical and neuropathological description of an HE patient with a rapid and fatal course.

A 67-year-old man with autoimmune hypothyroidism taking l-thyroxine 100 μg/day came to our observation because of 1-month history of apathy and speech difficulties. At admission in the neurological ward, fluent aphasia, disorientation, and spontaneous diffuse myoclonic jerks were present. Cranial CT and brain MRI were unremarkable. EEG evidenced rare diffuse theta-delta bursts. On laboratory investigations, we detected only a markedly raised titer of serum anti-TPO antibodies (3,790 UI/ml). CSF analysis disclosed very high protein concentration (126 mg/dL) with...
