目的探讨CT磁共振检查脑静脉及静脉窦血栓患者的临床表现及误诊漏诊现象。方法 17例脑静脉及静脉窦血栓患者,均行CT磁共振检查,探讨其临床表现与误诊漏诊原因。结果 CT主要表现为静脉窦区出现条状高密度影、受累脑静脉出现斑点样或条状高密度影、脑实质内低密度影表现以及Delta征;MR表现主要为窦静脉内短T1长T2信号;误诊率为23.5%,漏诊率为5.9%。结论脑静脉及静脉窦血栓影像学表现复杂,一定要正确认识静脉窦脑梗死病变、早期征象以及束带征,以减少误诊漏诊现象。
Objective To investigate the clinical manifestations and misdiagnosis and missed diagnosis of cerebral venous and venous sinus thrombosis in patients undergoing CT magnetic resonance imaging. Methods Seventeen patients with cerebral venous thrombosis and venous sinus thrombosis underwent CT magnetic resonance imaging (MRI) to explore the causes of their clinical manifestations and misdiagnosis. Results The main manifestations of CT in the sinus area showed a strip of high density, cerebral venous involvement involved spot-like or strip-like high density, intraparenchymal low density and Delta sign; MR mainly sinus venous short T1 T2 Signal; misdiagnosis rate was 23.5%, missed diagnosis rate was 5.9%. Conclusion Cerebral venous and venous sinus thrombosis complicated by imaging, we must correctly understand the lesions of the sinus infarction, early signs and band syndrome, in order to reduce misdiagnosis and missed diagnosis.
