脊髓梗死的临床和MRI特点分析

Analysis on clinical manifestations and MRI features of spinal cord infarction

目的探讨脊髓梗死的临床及MRI特点。方法回顾分析11例脊髓梗死病例的临床及MRI资料。结果脊髓梗死急性起病,呈卒中样病程。主要表现为疼痛、瘫痪、分离性感觉障碍及括约肌功能障碍。MRI T1WI低信号,T2WI高信号,DWI高信号。横轴位显示病变位于脊髓前2/3区域。结论脊髓梗死表现为脊髓前动脉综合征,MRI可多方位、多参数扫描,为诊断提供重要依据。

Objective To study the clinical manifestations and MRI features of spinal cord infarction.Methods Clinical manifestations and MRI data were retrospectively analyzed in 11 patients with spinal cord infarction.Results All 11 cases had an acute onset and a stroke-like course.Main clinical manifestations included pain,paralysis,dissociated sensory disturbance and sphincter dysfunction;MRI features： the infarction lesions appeared hypointense on T1WI and hyperintense on T2WI,DWI.From axial plane of MRI,the infarction lesions were found in the anterior 2/3 of spinal cord.Conclusion Anterior spinal artery syndrome is main clinical feature of spinal cord infarction;MRI examination can supply important diagnostic evidence for spinal cord infarction by different axis and multi-parameter scanning.
