摘　　要：目的探讨出血性脑梗死(HI)的MRI特征性表现及与临床关系。方法分析30例HI患者的MRI表现和临床资料。结果HI以发病2周内常见,约占76.7%。不同部位脑梗死HI的出血形态、位置不同:脑叶HI15例(50.0%),脑回状、斑片状出血位于皮层和/或皮层下白质;脑深部HI(基底节及丘脑)10例(33.3%);小脑HI4例(13.3%),斑片状、线状出血位于梗塞区内、边缘;混合型2例(6.7%)。T2*WI呈低信号。结论HI的MRI表现与脑梗死部位、面积有密切关系。T2*WI有助于HI的检出。脑梗死患者病情加重或考虑大面积脑梗死应在2周内进行影像学复查,以利于HI的早期诊断和治疗。Objective To assess the MR image characterization of hemorrhagic infarction（HI）and its relationship with clinical manifestations.Methods The MRI manifestations and clinical data of 30 cases with HI were retrospectively analyzed.Results HI often appeared in 2 weeks after cerebral infarction,about 76.7%.The shape and location of hemorrhage were different in HI patients with different position of infarction..In 15 patients（50.0%） the HI limited in brain lobes,hemorrhage located in cortex and/or subcortical white matter with patch border or brain gyrus like.In 10 patients（33.3%） HI limited in deep part of brain and HI located in deep part or boundary with patch border or line-like.In 4 patients（13.3%）HI limited in cerebellum and HI located in deep part or boundary with patch border or line-like.In 2 patients（6.7%）HI involved brain lobe and deep part.T2^＊WI showed low signal.Conclusion There are typical manifestations of MRI in HI,and it is closely related with the position and area of cerebral infarction.If patient＇s condition becomes more serious or large area infarction is considered,CT/MRI should be recheck in 2 weeks in order to the early diagnosis and treatment of HI.
