Mamillary body enhancement on MR as the only sign of acute Wernicke encephalopathy.
نویسندگان
چکیده
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.

I found the article “Gadolinium-Enhanced MR Findings in a Pediatric Case of Wernicke Encephalopathy” quite interesting and exquisitely illustrated (1). In the body of the paper and the legend of their Figure 1, however, the authors report that the signal intensity of the mamillary bodies appeared normal on the T2-weighted scans. To my view the mamillary bodies appeared of higher signal intensit...

This report describes the postcontrast MR findings of Wernicke encephalopathy seen in a malnourished 11-year-old boy. The examination showed increased signal on T2-weighted images in the periaqueductal gray matter and medial thalami. On T1-weighted acquisition, these areas showed decreased signal intensity, but on postcontrast T1-weighted examination, they showed moderately intense enhancement....
