We report a case of atretic parietal cephalocele with a persistent parietal falcine sinus and partial absence of the straight sinus. The direct puncture angiographic study demonstrated that there was a major venous channel through the parietal skull defect. From the embryological point of view, this association may provide us with possible pathoetiologic evidence of congenital sinus pericranii is one of the alternative venous drainage pathways to compensate venous outflow in the cases of intracranial developmental anomalies.
我们报告一例闭锁性顶叶脑膨出合并持续性顶叶大脑镰窦及部分直窦缺如的病例。直接穿刺血管造影研究显示，存在一条穿过顶骨颅骨缺损的主要静脉通道。从胚胎学角度来看，这种关联可能为我们提供先天性颅骨静脉窦的可能病因学证据，即它是颅内发育异常情况下补偿静脉流出的替代静脉引流途径之一。
