MR findings in Hashimoto encephalopathy.
نویسندگان
چکیده
A 35-year-old Korean woman had Hashimoto encephalopathy of varying MR imaging appearance over 5 years that ranged from that of transient subcortical ischemia to that of gradually evolving multifocal signal intensity change accompanied by unilateral cerebellar atrophy. Thus, the MR imaging appearance of Hashimoto encephalopathy may simulate an ischemic stroke, multiple tumors or granulomas, or even a degenerative process.

Steroid-responsive encephalopathy associated with autoimmune thyroiditis presenting with diffusion MR imaging changes.
Steroid-responsive encephalopathy associated with autoimmune thyroiditis (SREAT) presents with focal or diffuse nonenhancing MR imaging abnormalities in 50% of patients with SREAT during subacute exacerbation. Vasculitic changes in biopsy studies as well as the elevation of antithyroid antibodies and CSF protein suggests an inflammatory cause. We report the case of a patient with SREAT with cha...
متن کاملProton MR spectroscopy in Wernicke encephalopathy.
Wernicke encephalopathy is caused by thiamine deficiency. Although the clinical picture has been well established for some time, clinical diagnosis is attained in only 20% of the cases. MR imaging techniques contribute to early diagnosis of Wernicke encephalopathy. We herein report MR imaging and proton MR spectroscopic findings for a patient with clinical and biochemical features consistent wi...
متن کاملValproate-induced encephalopathy: assessment with MR imaging and 1H MR spectroscopy.
The anticonvulsant agent valproate (VPA) may cause hyperammonemic encephalopathy. Magnetic resonance imaging (MRI) and proton MR spectroscopic (MRS) findings in a patient with VPA-induced hyperammonemic encephalopathy are described. MRI showed a metabolic-toxic lesion pattern with bilateral T2-hyperintense lesions in the cerebellar white matter and in the globus pallidus. MR spectroscopic findi...
متن کاملWernicke encephalopathy: MR findings in five patients.
Wernicke encephalopathy is a disease usually related to chronic alcoholism. The clinical diagnosis is often difficult to establish, and CT is unable to provide specific findings. MR follow-up studies in five patients affected by Wernicke encephalopathy were performed with the aim of establishing the sensitivity of MR in depicting the typical diencephalic/mesencephalic lesions. All subjects had ...
متن کاملDiffusion-weighted MR imaging findings of acute necrotizing encephalopathy.
Multiple, symmetrical brain lesions affecting the bilateral thalami and cerebral white matter, which often show a concentric structure on CT and MR images, characterize acute necrotizing encephalopathy (ANE) of childhood. We describe the imaging findings of a 2-year-old child with ANE obtained with diffusion-weighted MR imaging. We discuss the significance of these findings, as well as the path...
