In the preceding part, galenic dysgenesis was stated to be a diagnostic hallmark of dorsal cyst malformations. Failed formation of the galenic drainage system conducts the diencephalic drainage laterally into the transverse sinuses as in the embryonal stage, and it is frequently associated with arrested descent of the torcular portion or other anomalies of the dural sinuses. Highly malformed structures of the deep cerebral veins and the dural sinuses seen in this malformation are correctly interpreted in comparison with findings of venous injection studies performed in human fetuses. Pathogenesis of this malformation is also discussed on the basis of embryological studies of the dural sinuses and falcotentorial structures.
在前一部分中，盖伦静脉发育不全被认为是背侧囊肿畸形的诊断标志。盖伦静脉引流系统形成失败会使间脑引流像在胚胎期一样侧向进入横窦，并且它常与窦汇部分下降受阻或硬脑膜窦的其他异常相关。与在人类胎儿中进行的静脉注射研究结果相比，这种畸形中所见的大脑深静脉和硬脑膜窦的高度畸形结构得到了正确的解释。还基于对硬脑膜窦和小脑幕结构的胚胎学研究讨论了这种畸形的发病机制。
