RT Journal Article SR Electronic T1 Mamillary body enhancement on MR as the only sign of acute Wernicke encephalopathy. JF American Journal of Neuroradiology JO Am. J. Neuroradiol. FD American Society of Neuroradiology SP 172 OP 174 VO 15 IS 1 A1 M E Shogry A1 J T Curnes YR 1994 UL http://www.ajnr.org/content/15/1/172.abstract AB We report a case of Wernicke encephalopathy in which the only sign of acute disease was enhancement of the mamillary bodies. This case demonstrates the utility of gadolinium enhancement at MR imaging as a means of diagnosing or confirming the syndrome of Wernicke encephalopathy even in the absence of atrophy or T2 abnormalities within the diencephalon and mesencephalon.
