1 Hashimoto encephalitis.
Hashimoto encephalitis. A 41-year-old woman presented with gradually worsening headaches and memory impairment without the development of psychosis or seizures. MR imaging of the brain (time, 0) demonstrates T2-FLAIR hyperintensity in the inferior left temporal lobe (A) without evidence of restricted diffusion (B and C). MR imaging of the brain (time, 21 days) demonstrates enlargement of the lesion on T2-FLAIR (not shown) without postcontrast enhancement (D). MR imaging of the brain (time, 3 months) demonstrates resolution of the prior lesion (not shown) but development of similar T2-FLAIR hyperintensity in the right frontoparietal junction (E). A subsequent scan at approximately 5 months shows near-complete resolution of that lesion with a new T2-FLAIR hyperintense lesion more posteriorly (F). A follow-up scan (G and H) nearly 1 year from onset shows complete resolution of the imaging abnormalities. B.P. Kelley et al.
