The Dandy-Walker malformation (DWM) is hydrocephalus that primarily affects the fourth ventricle, whose overdistention involves also the aqueduct and third ventricle. However, just the opposite is true in the Arnold-Chiari malformation (ACM) since the hydrocephalus is limited to the lateral ventricles which squeeze the third ventricle between them and compress the aqueduct and fourth ventricle. The evidence indicates that both result from hydrodynamic stresses in embryonal and early fetal life. This communication is offered in rebuttal to some statements in an otherwise authoritative and comprehensive article.
丹迪-沃克畸形（DWM）是一种主要影响第四脑室的脑积水，其过度扩张还累及导水管和第三脑室。然而，在阿诺德-奇亚里畸形（ACM）中情况恰恰相反，因为脑积水仅限于侧脑室，侧脑室将第三脑室挤压在它们之间，并压迫导水管和第四脑室。有证据表明，两者均源于胚胎期和胎儿早期的流体动力应力。本文旨在反驳一篇原本权威且全面的文章中的一些观点。
