【摘要】 目的探讨弓形体脑病的MRI表现。方法本组病例20例。所有患者均接受了MRI及血清学免疫学(ELISA法)检查。5例行CT引导下的立体定向活检术。17例做了MRI增强扫描。15例进行了MRI复查。本组病例均进行了抗弓形体治疗。结果多数病灶位于大脑半球灰白质交界处(8例),其次为侧脑室周围(6例),病变多发为其特点(18例)。增强扫描绝大数病变呈不同程度强化(17例),其中以片状或斑片状强化最为常见(9例),其次为环形或半环形强化(7例)。血清学免疫学检查所有病例IgM或IgG抗体均呈阳性。所有病例抗弓形体治疗均有效。结论MRI对确定弓形体脑病的部位、范围及观察病灶演变情况、评价治疗效果有重要价值。更多还原

【Abstract】 Objective To study the MRI features of toxoplasmosis encephalopathy.Methods There were totally 20 cases in the group,all patients accepted the examinations of MRI and immunisation sylum(EIISA) with Gd-DTPA enhanced MRI in 17 cases and repeted MRI in 15 cases.5 cases undengone stero-orientation biopsy under CT guided.Results Most of the focus situated at the juncture of gray and white matter of cerebral hemisphere (8 cases) and around the lateral ventricle (6 cases).The lesion was multiple .The lesions had different degrees of contrast enhancement after enhanced scans (17 cases),among them,the patchy enhancement was most commonly seen (9 cases),secondarily was circular or semicircular enhancemeut (7 cases).The immunological serum examination in all the cases were positive IgM or IgG.The treatment for anti-toxoplasma was in effect for all the cases.Conclusion MRI is of significant value in definiting the involved location,extent,time course of toxoplasmosis encephalopathy,and also evaluating the effect of therapy.更多还原
