摘　　要：分析了７例原发性脑静脉窦血栓形成的ＣＴ和ＭＲＩ征象。经静脉期脑血管造影和手术病理证实分别为５和１例，重复ＭＲＩ确诊１例。５例血栓在上矢状窦，１例在右侧横窦，１例位于左侧大脑中静脉。ＣＴ扫描２例显示脑静脉（窦）血栓直接征象，２例为非特征性改变，３例无阳性发现。２例行ＭＲＩ检查，受累静脉窦内Ｔ１、Ｔ２加权像上均为高信号，１例治疗后复查高信号消失。５例造影明确了静脉窦闭塞的部位和程度，２例可见静脉窦闭塞后逆流现象。Computed tomography(CT) and the magnetic resonance(MR) images of 7 patients with primary cerebral sinus and cortical vein thrombosis,confirmed by angiography, were reviewed.The thrombosis of superior sagittal sinus,right transverse sinus and left medial cerebral vein was in 5,1,and 1 respectively.CT scans showed direct thrombosis signs within the affected sinus and vein in 2,nonspecific and normal in 2 and 3 respectively.Hish-intensity signal was seen from the thrombus within the affected cerebral sinus on T1、T2 WI in 2 patients with MRI,and disappeared in 1 of them after about one month anticoagulant therapy.Angiographically, all of 5 patients revealed occlusive location and degree of the affected cerebral sinus and 2 of them showed the cerebral cortical venous collaterals.
