急性單純胼胝體梗死5例分析

【摘 要】 目的探討急性胼胝體梗死的臨床及影像學表現，提高對該疾病的認識。方法回顧分析2009年2月-2014年2月我院住院治療的2020例急性腦梗死患者中，資料完整的5例急性單純胼胝體梗死患者的資料特點。結果胼胝體梗死發生率0.25%(5/2020)，主要危險因素是高血壓、糖尿病、高脂血癥，動脈粥樣硬化是其主要的病因。5例主要臨床表現為運動障礙和認知功能障礙。頭顱MRI檢查顯示胼胝體體部3例、膝部1例、壓部1例梗死。結論急性胼胝體梗死發生率低，胼胝體梗死因部位不同而臨床表現各異，應重視其表現的多樣性，頭顱MRI特別是DWI對其診斷有重要作用。

(Department of Neurology，Baoshan Branch of Shanghai First People's Hospital，Baoshan District，Shanghai，200940)【Abstract】 ObjectiveTo explore the clinical and medical imageology characteristics of the acute corpus callosum infarction and improve the understanding of this disease.MethodReview and analyze the characteristics and documentation of 5 out of 2020 cerebral infarction patients treated in our hospital from January 2009 to February 2014.ResultThe incidence of this disease was 0.25%(5/2020)， where high blood pressure，hiperlipemia 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.ConclusionIncedence 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 MRI，especially DWI，plays an important role to the topical diagnosis of corpus callosum infarction.
