摘要 目的探讨MRI弥散加权成像(DWI)对垂体瘤梗塞性卒中的诊断价值。方法收集29例病理学检查确诊为垂体瘤梗塞性卒中患者的术前影像学及临床资料,其中7例患者术前均行包含DWI序列的颅脑MRI平扫检查,对其DWI序列的成像特点进行分析。结果7例患者中,在DWI序列上仅1例患者肿瘤表现为弥漫性高信号,1例患者肿瘤表现为斑片状高信号,其余5例患者肿瘤未见高信号。结论DWI成像对垂体瘤梗塞性卒中无明显特异性诊断价值。 Objective To investigate the value of diffusion-weighted imaging(DWI)in the diagnosis of infarcted pituitary adenoma-associated apoplexy.Methods Preoperative imaging data and clinical data were collected from 29 patients with pathologically confirmed infarcted pituitary adenoma-associated apoplexy,among whom 7 patients underwent cranial magnetic resonance imaging including DWI sequence before surgery,and DWI features were analyzed.Results Among the 7 patients undergoing DWI,1 had diffuse hyperintensity,1 had patchy hyperintensity,and 5 had no hyperintensity.Conclusion DWI has no specific value in the diagnosis of infarcted pituitary adenoma-associated apoplexy.
