摘要
目的:探讨分支动脉粥样硬化病(BAD)的发病机制、临床特征和影像学诊断,并与腔隙性脑梗死相鉴别,提高对BAD的认识。方法:分析3例BAD患者的临床表现和影像学特征,并结合文献复习进行研究。结果:3例BAD患者临床分别表现为短暂脑缺血发作、纯运动型腔隙综合征和运动感觉型腔隙综合征;MRI水平位断层均显示侧脑室旁呈连续3～5个层面的斑点(片)状长T1、长T2信号,冠状位可见纵长形似"逗号"样的"巨大腔隙梗死"灶。结论:BAD是一种新型脑梗死,对临床疑似腔隙性脑梗死尤其是"巨大腔隙性梗死"而又不能完全符合诊断标准的病例,建议作头颅MRI冠状位检查以提高对BAD的诊断,有利于进一步治疗。
Aim： To analyze the pathogenesis, clinical characteristics, imaging diagnosis of the branch atheromatous disease （BAD）, and distinguish with lacunar infarction, in order to improve the understanding of the disease. Methods： 3 cases of patients on clinical manifestations and imaging features were analyzed and the literature was reviewed. Results： The three cases are manifested differently as transient ischemic attack, pure motor lacunar syndrome and sensorimotor lacunar syndrome; the 3 cases all on MRI axial section shows continuous 3-5 sections of long Tl-weighted, long T2-weighted signal as spots（patching） on the side lateral ventricle, coronal MR/show the comma shape of ＂huge lacunar infarction＂. Conclusion： BAD is a new type of cerebral infarction. As to the cases suspected of lacunar infarction, especially ＂huge lacunar infarction＂ and cannot completely matching the criteria for diagnosis, it is suggested that coronal cerebral MRI inspection should be made to improve the diagnosis and treatment for further.
