Abstract
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. Also noted on the postcontrast examination was mamillary body enhancement.
摘要
本报告描述了一名营养不良的11岁男孩的韦尼克脑病的对比增强磁共振成像（MR）表现。检查显示中脑导水管周围灰质和丘脑内侧在T2加权图像上信号增强。在T1加权成像上，这些区域信号强度降低，但在对比增强T1加权检查中，它们显示出中等程度的强化。对比增强检查还发现乳头体强化。
