摘　　要：目的:探讨颅内静脉窦血栓形成的CT影像学特征,为颅内静脉窦血栓形成的CT诊断提供参考。方法:回顾性分析32例颅内静脉窦血栓形成患者的CT扫描图像,对其重新阅片,分析CT扫描的影像学特点及特有征象。结果:颅内静脉窭血栓形成CT扫描病灶多为低密度影,面积较大,或可见低密度灶内出血征象,在位于中线位置的颅内静脉窦血栓形成者可见对称性病变,静脉窦内可见高密度影充填。结论:颅内静脉窦血栓形成CT扫描可出现特征性影像学特点,能够为其诊断及鉴别提供影像学依据。Objective： To investigate the imaging characteristic ofCT scaing on thrombosis of intracranial venous sinus,and provied reference for diagnosis with imageology.Methods：32 imaging of CT scaing that had been prognosized thrombosis of intracranial venous sinus were analyzed with retrospective ways, to examine imaging again,and analyzed the characteristic of image and typical image sign Results： Mostly focus of CT scaning on thrombosis of intracranial venous sinus were low-density and large-area, hemorrhage sign of high-density on sometimes, symmetric focus could be found when loction of thrombosis of intracranial venous sinus was in neutral line, sinus venosus were filled with high-density.Conclusions：Image of CT scaning on thrombosis of intracranial venous sinus could had typical imageology image,and provided reference for diagnosis and antidiastole.
