摘要 目的观察1例子宫内膜癌脑转移患者的临床、影像学和经颅多普勒超声(trascranial dopler,TCD)脑微栓子监测的特点和治疗前后的动态变化。方法对1例子宫内膜癌脑转移患者治疗前后对双侧大脑中动脉(MCA)或大脑后动脉(PCA)进行TCD微栓子监测(发病后1d、3d、4d、7d、9d、1个月、3个月、8个月及1年)和头颅平扫或/和增强MRI(发病后3d、9d、22d、3个月、5个月、8个月及1年)检查。结果患者临床以短暂性脑缺血发作样症状起病。放化疗前头颅MRI示双侧大脑半球及小脑的T2WI、T2FLAIR、DWI高信号、可强化的多发小结节灶,主要累及皮质;双侧MCA均可监测到微栓子信号(Microembolic signals,MES)。治疗后随访1年期间无临床症状,未监测到MES,头颅MRI示原有病灶缩小或消失,无新发病灶。结论恶性肿瘤脑转移患者TCD监测有可能发现MES,可能是由于血流中微小瘤栓所致,但并不一定伴有临床症状或影像学上可见病灶。颅内多发病变患者发现MES时提示有恶性肿瘤血行转移致肿瘤性脑栓塞的可能。
