垂体卒中的临床与磁共振特征

目的:探讨垂体卒中的临床和MRI特征。方法:分析13例垂体卒中患者的临床和头MRI资料。结果:76.9%的患者卒中前无垂体瘤表现,84.6%的患者发病前无明显诱因。典型临床表现为头痛、呕吐及视力障碍等。MRI检查发现,瘤内出血8例,表现为T1WI等信号合并高信号,T2WI像为高信号;肿瘤内坏死3例,表现为T1WI低信号,T2WI高信号;出血合并坏死2例,表现为T1WI高低混杂信号,T2WI高信号。结论:垂体卒中临床表现多样,易漏诊误诊。MRI检查结合临床,对诊断和选择治疗方案有重要价值。

Study on Clinical and MRI Characteristic of Pituitary Apoplexy

Objective: To explore the diagnostic value of clinical and MR1 characteristics of pituitary apoplexy. Methods: The clinical and MR1 data of 13 cases with pituitary apoplexy were analyzed. Results: 76. 9% of pituitary apoplexy have no manifestations of hypophysoma. The clear accasions are not found before onset in 84. 6% patients. The typical manifestations are headache, vomiting and hypopsia. MR1 findings of 13 cases included: 8 cases of hemorrhage in tumors with iso-signal and high signal on T1 WI and high signal on T2WI; 3 cases of necrosis with low signal on T1 WI and high signal on T2WI; 2 cases of hemorrhage and necrosis with medley signal. Conclusion: Because clinical manifestations have variety. That MR1 is combined with clinical data are of great value for the diagnosis and therapy of pituitary apoplexy.
