We report a patient with severe anorexia nervosa, treated with temporary total parenteral nutrition (TPN), in whom reversible hyperintensity of the anterior pituitary gland was seen on T1-weighted MR images. The anterior pituitary was isointense with white matter before TPN therapy and became markedly hyperintense after 3 months of treatment. The intensity normalized after TPN therapy was discontinued. The transient hyperintensity was also seen in the basal ganglia and dorsal brain stem. We believe the hyperintensity of the anterior pituitary may be attributed to the TPN therapy.
我们报告了一名患有严重神经性厌食症的患者，接受了临时全胃肠外营养（TPN）治疗，在T1加权磁共振成像上可见垂体前叶可逆性高信号。在TPN治疗前，垂体前叶与白质信号强度相同，治疗3个月后变得明显高信号。停止TPN治疗后信号强度恢复正常。基底节和脑桥背侧也可见短暂性高信号。我们认为垂体前叶的高信号可能归因于TPN治疗。
