Abstract

Hashimoto's encephalopathy (HE) is an uncommon syndrome with the characteristic triad of positive antithyroid antibodies (most commonly antibodies to thyroid peroxidase), response to steroids, and clinical picture presenting either as stroke-like pattern of focal neurological deficit or slowly progressive cognitive impairment. Myoclonus or tremors, seizures, and psychosis are other associated features which can be seen in HE. Herein, we report a girl with an uncommon presentation of orthostatic axial and myoclonic jerks in bilateral lower limbs in a case of HE.
