目的探讨胼胝体梗死的发生率、病因、临床表现、影像学特点以及预后转归。方法回顾性分析安徽省立医院近4年来33例胼胝体梗死患者的临床和影像学资料。结果该病发生率仅2.05%;平均年龄为(62.50±8.93)岁,主要危险因素是高血压、高脂血症和糖尿病;临床表现以偏瘫(93.9%)最多见,典型的离断综合征较少见;影像学显示梗死部位以体部和压部多见,常累及基底节区、半卵圆中心等部位;经治疗后22例患者肢体运动功能好转,5例恶化,6例无明显变化。结论胼胝体梗死相对发病率低,临床表现复杂多样,其特异性失连接现象易被掩盖,头颅MRI对胼胝体梗死定位诊断具有重要意义。
Objective To investigate the incidence of corpus callosum infarction, etiology, clinical manifestations, imaging features and prognosis prognosis. Methods The clinical and imaging data of 33 patients with corpus callosum infarction in Anhui Provincial Hospital during the recent 4 years were retrospectively analyzed. Results The incidence of this disease was only 2.05%. The average age was (62.50 ± 8.93) years old. The main risk factors were hypertension, hyperlipidemia and diabetes. The clinical manifestations were hemiparesis (93.9%), typical sever syndrome Rare; imaging showed that the infarction to more common body and pressure, often involving the basal ganglia, hemizygous center and other parts; after treatment, 22 patients improved limb motor function, 5 cases of deterioration, 6 cases no significant Variety. Conclusions The relative incidence of corpus callosum infarction is low, the clinical manifestations are complex and diverse, and its specific loss of connection is easily obscured. MRI of the head is of great significance in the localization diagnosis of the corpus callosum infarction.
