He attended the general casualty but no cause was found. He was discharged with a diagnosis of possible migraine. However, the pain persisted and he re-attended the casualty 2 days later. He was found to have bilateral optic disc swellings and an urgent MRI scan was requested. Full blood count revealed high platelet count (thrombocythemia) but otherwise all the other tests were normal 脑静脉 窦血栓 上矢状窦血栓 （superior sagittal sinus thrombosis，SSST） Clinical History: 17-year-old female who presents with a four day history of headaches and a seizure immediately prior to admission. There is no significant past medical history. Findings: An axial noncontrasted CT image through the brain demonstrates cerebral edema within the left frontal lobe and deep gray matter. In addition, there is hyperattenuation within the region of the straight sinus. Petechial hemorrhage as well as edema is seen within the left frontal lobe An angiogram demonstrates occlusion of the anterior one half of the superior sagittal sinus as well as occlusion of the deep venous system bilaterally. 脑静脉 窦血栓 上矢状窦血栓 （superior sagittal sinus thrombosis，SSST） ●预后： 单纯上矢状窦血栓在数周或数月后可再通，颅内压恢复正常，预后良好。 如果累及到其他脑静脉窦或脑静脉，而未能得到及时有效的治疗，其颅压高将持久存在，严重者可造成死亡。 脑静脉 窦血栓 上矢状窦血栓 （superior sagittal sinus thrombosis，SSST） ●横窦和乙状窦统称为侧窦。 ●
