垂体卒中的MRI诊断与手术、病理对照研究（附52例分析）

目的探讨垂体卒中的MRI不同表现及鉴别诊断.材料和方法对52例垂体卒中患者行常规TSE序列/Gd-DT-PA MRI增强扫描、CT扫描,并与手术和病理结果进行对照.结果94.2%的垂体卒中发生于垂体巨大腺瘤或大腺瘤,65.4%的病例MRI表现为T1高信号或等、高混杂信号,T2高信号或等、高混杂信号,MRI诊断垂体卒中准确率达100%.结论MRI对于垂体卒中的诊断价值优于CT,MRI平扫即能明确诊断.

Diagnosis of Pituitary Apoplexy: Correlation of MRI Imaging with Operative and Pathological Findings (Analysis of 52 Cases)

Purpose: To study various MRI features and differential diagnosis of pituitary apoplexy (PA). Materials and Methods: 52 patients with PA were evaluated with MRI including TSE and Gd DTPA enhanced scanning?CT scan and correlated with operation and pathological findings. Results: 94.2% of PA occured in macroadenoma or giant pituitary adenoma, 65.4% cases showed hyperintense or iso to hyperintense on T 1 weighted, hyperintense or iso to hyperintense on T 2 weighted. Diagnostic accuracy was 100 percent in MRI. Conclusion: MRI has been proven to be superior to CT in diagnosis of PA. Enhanced scanning was found not to contribute significant when evidence of hemorrhage was already assessed on non enhanced MRI.
