title: Computed tomography findings in thiamine deficiency-induced coma.
abstract: Although brain magnetic resonance imaging is a more sensitive diagnostic tool in the evaluation of coma, noncontrast head computed tomography (CT) may demonstrate highly specific findings in some cases of coma. We present a case of thiamine deficiency-induced coma associated with acute necrosis of fornices documented on CT and review cardinal neuroimaging features of Wernicke encephalopathy. Acute fornices necrosis is a novel finding on head CT suggestive of thiamine deficiency.
