垂体柄阻断综合征的MRI诊断价值

MRI diagnostic value of pituitary stalk interruption syndrome

目的分析垂体柄阻断综合征的MRI表现,提高诊断水平。材料与方法回顾性分析15例MRI证实的垂体柄阻断综合征患者的临床及MRI表现。结果 15例均有生长激素缺乏,2例为单一生长激素缺乏,余13例合并其他多种腺垂体激素缺乏。MRI显示15例患者均垂体柄缺如及垂体后叶异位至漏斗隐窝处,13例垂体前叶变小但信号正常,2例垂体前叶高度信号正常。结论垂体柄阻断综合征具有特征性的MRI表现,MRI是诊断该病最佳的影像学检查方法。

Objective： To analyze MRI features of pituitary stalk interruption syndrome to improve diagnostic level. Materials and Methods： The clinical and MRI features of 15 patients with pituitary stalk interruption syndrome proved by MRI were retrospectively analyzed. Results：In all 15 cases, it happened growth hormone deifciency, 2 cases for a single growth hormone deifciency,the rest 13 cases combined with multiple hormone deifciency. With MRI examination,the pituitary stalk was not shown in all 15 cases and ectopic posterior lobe located in infundibulum in all 15 cases,decreased anterior lobe with normal signal in 13 cases, normal height and signal anterior lobe in 2 cases. Conclusion： MRI findings of pituitary stalk interruption syndrome were characteristic, MRI was the best imaging modality for the diagnosis of pituitary stalk interrup tion syndrome.
