What are the possible diagnoses of bilateral lesions in the thalamus?
Wernicke encephalopathy, low-grade astrocytoma (bilateral thalamic glioma), the artery of Percheron occlusion, Creutzfeldt-Jakob disease, among others
Large bilateral and the symmetrical expansive/infiltrative lesion in the thalamus and midbrain roof, with a hyperintense signal in T2 / FLAIR and intermediate in T1, determining compression in the contiguous portions of the supratentorial ventricular system, without conditioning aqueduct stenosis. There is small impregnation of nodular contrast in the posteromedial aspect of the left thalamic lesion and no diffusion restriction was seen.
