目的:分析空蝶鞍综合征(ESS)MR表现及临床意义。材料和方法:经MRI诊断为ESS者34例, 根据垂体压缩程度分Ⅰ、Ⅱ两型。比较两型的MR所见和临床表现。结果:Ⅰ型ESS显示垂体柄后移7例, 占35%(7/20), 视交叉上抬3例, 占15%(3/20);Ⅱ型ESS显示垂体柄后移11例, 占78%(11/14), 视交叉上抬8例, 占57%(8/14), 二者有明显统计学差异(P<0.01).Ⅱ型ESS的垂体后叶信号变为等信号的发生率比Ⅰ型高。但比较Ⅰ型与Ⅱ型的主要临床表现无有意义差别。结论:ESS的MR表现及分型对临床认识和处理本病有一定参考价值。 |

Purpose:To analyse the MR manifestations and clinical significance of Empty Sella Syndrome(ESS).Materials and Methods:Thirty four cases of ESS were diagnosed by a MR system.It can be divided into the Ⅰ and the Ⅱtypes,according to the degree of compression of the pituitary.The Ⅰ type of ESS was compared with the Ⅱtypes on the MR findings and clinical manifestations.Results:ESS appeared as hypophyseal stalk retroposition in 7 cases (7/20) and optic chiasm elevation in 3 cases (3/20),which were graded as the Ⅰ type;hypophyseal stalk retroposition in 11 cases(11/14),optic chiasm elevation in 8 cases(8/14),they were graded as the Ⅱ type,both ESS were significantly different(P<0.01).Isointence signal of neurohypophysis were significantly higher in the Ⅱ type than the Ⅰ type.However,both types of ESS were not significantly different in main clinical findings.Conclusion:MR manifestations and classfication of ESS have diffinitive referential value from the point of view of clinical recognization and management. |
