积水性无脑畸形(大体)

此处打开颅骨来自一个7-9月的死产胎儿,以显示积水性无脑畸形。在这种情况下,会出现例如动脉阻塞的子宫病变,它导致广泛的脑梗死,典型地会累及大脑半球。剩下的是薄薄的皮质边缘或包绕液体腔的脑膜神经胶质组织。

The skull is opened in this third trimester stillborn fetus to reveal hydranencephaly. In this condition, there is an intrauterine event, such as an arterial occlusion, which leads to extensive cerebral infarction, typically involving the hemispheres. All that is left is a thin rim of cortex or glial tissue with meninges surrounding a fluid-filled cavity.
