目的分析颅内静脉窦血栓形成的临床特点，磁共振成像及磁共振血管造影对其诊断的价值。方法分析5例磁共振检查确诊的颅内静脉窦血栓形成病人的临床资料及影像学特点，其中男1例，女4例，年龄22～40岁。病后3～19天行磁共振检查，主要观察水肿、静脉性便死或出血、静脉窦内异常信号，部分病人复查时可见再通。结果5例颅内静脉窦血栓形成皆有明确原因，临床表现多样，主要为亚急性颅内压增高、抽搐、肢体瘫痪或昏迷。MRI常规SE序列T1、T2加权示窦内高信号，脑实质水肿或合并出血、硬死。磁共振脑血管造影（MRA）的PC法示静脉窦高血流信号丢失，2例分别于病后24、31天复查MRI，结果示再通。经降颅内压、抗凝、合并感染者予抗生素、激素治疗，5例均治愈。结论颅内静脉窦血栓形成是较为少见的脑血管病，且病情重，MRI／MRA可帮助确诊。早期治疗能明显改善预后。
Objective To analyze the clinical characteristics of intracranial venous sinus thrombosis, magnetic resonance imaging and magnetic resonance angiography in the diagnosis of its value. Methods Clinical data and imaging features of 5 patients with intracranial venous sinus thrombosis diagnosed by MRI were analyzed. There were 1 males and 4 females, aged 22-40 years old. 3 to 19 days after the disease underwent magnetic resonance imaging, the main observation of edema, venous stool or bleeding, sinus abnormalities within the signal, some patients can be recalled recheck. Results 5 cases of intracranial venous sinus thrombosis have a clear cause, clinical manifestations and diverse, mainly for subacute increased intracranial pressure, convulsions, limb paralysis or coma. MRI conventional SE sequence T1, T2 weighted sinus high signal, edema of the brain or merged bleeding, death. Magnetic resonance imaging of cerebrovascular angiography (MRA) of the PC method shows sinus venous high blood flow signal loss, 2 cases were reviewed after 24,31 days MRI, the results showed recanalization. After the intracranial pressure, anticoagulant, co-infected with antibiotics, hormone therapy, 5 patients were cured. Conclusion Intracranial venous sinus thrombosis is a rare type of cerebrovascular disease, and the severity of the disease, MRI / MRA can help confirm the diagnosis. Early treatment can significantly improve the prognosis.
