目的探讨单纯性胼胝体梗死的临床与影像学特点。方法回顾性分近20例单纯性胼胝体梗死患者的临床和影像学资料。结果本组全部伴高危因素;临床表现以偏瘫、共济失调和偏侧感觉障碍多见,影像学显示梗死部位以体部和膝部多见。经治疗后16例患者肢体运动功能好转,1例恶化,3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 clinical and imaging features of simple corpus callosum infarction. Methods The clinical and imaging data of nearly 20 patients with simple corpus callosum infarction were retrospectively analyzed. Results All patients were at risk. The clinical manifestations were hemiparesis, ataxia and unilateral sensory disturbance. Imaging showed that infarction was common in the body and knee. After treatment, 16 patients improved limb motor function, 1 case of deterioration, 3 cases no significant change. 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 corpus callosum infarction.
