Abstract

We have studied the subcommissural organ of two hydrocephalic brains, of 20 and 21 gestational weeks and of two normal brains, aged 19 and 23 gestational weeks. Both hydrocephalic cases presented a size reduction of the subcommissural organ compared to the normal cases; only in one case, there were also alterations of the morphological components of the subcommissural organ, suggesting different pathogenic relationships between hydrocephalus and dysplasia of the subcommissural organ.

摘要

我们研究了两例脑积水胎儿大脑的连合下器官，孕周分别为20周和21周，以及两例正常胎儿大脑，孕周分别为19周和23周。与正常情况相比，两例脑积水病例的连合下器官均出现体积减小；仅在一例中，连合下器官的形态学成分也有改变，提示脑积水与连合下器官发育异常之间存在不同的致病关系。
