急性单纯胼胝体梗死5例分析

Analysis of 5 Cases of Acute Simple Corpus Callosum Infarction

目的:探讨急性胼胝体梗死的临床及影像学表现,提高对该疾病的认识。方法回顾分析2009年2月-2014年2月我院住院治疗的2020例急性脑梗死患者中,资料完整的5例急性单纯胼胝体梗死患者的资料特点。结果胼胝体梗死发生率0.25%(5/2020),主要危险因素是高血压、糖尿病、高脂血症,动脉粥样硬化是其主要的病因。5例主要临床表现为运动障碍和认知功能障碍。头颅 MRI 检查显示胼胝体体部3例、膝部1例、压部1例梗死。结论急性胼胝体梗死发生率低,胼胝体梗死因部位不同而临床表现各异,应重视其表现的多样性,头颅 MRI 特别是 DWI 对其诊断有重要作用。

Objective To explore the clinical and medical imageology characteristics of the acute corpus allosum infarction and improve the understanding of this disease.Method Review and analyze the characteristics and documentation of5 out of 2020 cerebral infarction patents treated in our hospital from January 2009 to February 2014.Result The incidence of this disease was 0.25%(5/2020),where high blood pressure,hiperipemia and diabetes mellitus has been found main risky factors while atherosclerosis as the main cause.Among the 5 cases,main clinical manifestations were movement and cognitive dysfunction.Cranial MRI scan showed three cases of corpus callosum body,one case of knee,and the other one of infarction press section.Conclusion Incedence rate of corpus callosum infarction was low,clinical manifestations of corpus callosum infarction vary from the body parts and attention should be paid to the diversity of its manifestation.Skull MRL,especially DWI,plays an important role to the topical diagnosis of corpus callosum infarction.
