This paper describes the CT findings in five cases of cerebral and cerebellar sinovenous occlusion. Characteristic CT findings are the visualisation of the thrombosed sinuses and veins, known as the "filled triangle" and the "cord sign" on the control scan, and the "empty triangle" with tentorial and gyral enhancement after contrast enhancement. The high incidence of thrombosed internal cerebral veins and superior cerebellar veins with sinus thrombosis in children is remarkable. CT with both control and contrast enhanced scans will probably provide the correct diagnosis in the majority of cases.
本文描述了5例大脑和小脑静脉窦闭塞的CT表现。特征性CT表现为血栓形成的静脉窦和静脉显影,在平扫上称为“充盈三角”和“条索征”,增强扫描后可见天幕和脑回强化的“空三角”。儿童脑内静脉和小脑上静脉血栓形成合并静脉窦血栓的发生率较高。平扫和增强扫描相结合的CT检查可能在大多数病例中提供正确诊断。
