The signal abnormalities found on MRI in the basal ganglia in patients with an increased plasmatic level of manganese are well known. We report a case with a hyperintense signal in a patient with a high plasmatic level of manganese due to long term parenteral nutrition. The normal signal intensity of T2-weighted imaging in the anterior pituitary gland helps to differentiate the increased signal intensity of T1 weighted imaging due to deposition of manganese from hemorrhagic or fatty lesions.
血浆锰水平升高的患者，其基底节区磁共振成像（MRI）上发现的信号异常是众所周知的。我们报告一例因长期肠外营养导致血浆锰水平高的患者，其出现高信号。垂体前叶T2加权成像的正常信号强度有助于鉴别因锰沉积导致的T1加权成像信号增强与出血性或脂肪性病变。
