The term hydranencephaly is deried from the combination of the words hydrocephalus and anencephaly, although it differs from both these entities.

水脑畸形这一术语出自于脑积水和无脑畸形两个术语，尽管它与这二种病均不同。

These include anencephaly, spina bifida and cephalocele.

包括无脑畸形、脑膨出和脊柱裂。

In contrast to hydrocephalus, fetuses with hydranencephaly hae a complete lack of cerebral tissue, and in contrast to anencephaly, there is coering by bone, skin, dura, and leptomeninges(33) Fig.

与脑积水相比较，患有水脑畸形的的胎儿完全缺乏脑组织，而与无脑畸形相比，它有骨、皮肤、硬脑膜和蛛网膜覆盖（图10-26）。

For example, neural tube defects （NTDs--anencephaly, spina bifida, encephalocele, myelomeningocele） usually have multifactorial causes, although they also have many specific known single-gene, chromosomal, and environmental causes.

例如神经管缺陷（NTD，包括无脑，脊柱裂，脑膨出，脊髓脊膜膨出）通常有多基因造成，虽然也有许多已知的单基因，染色体和环境原因。

Results:In experimental group,all 20 rats have unifocal masses and S-100 protein without extracerebral metabasis and the extracranial extension. The size, the site and morphology of all tumors are almost the same.

结果：脑胶质瘤组，20只大鼠经MRI平扫、增强扫描和形态学检查证实均有单灶肿块，且肿瘤部位、大小、形态基本一致，无脑外转移和颅外扩散，经免疫组织化学染色检测S-100蛋白均为阳性。

Radionuclide dynamic cisternography plays an important role in assessing whether there is cerebrospinal rhinorrhea and determining the concrete situation of leakage.

结论核素脑池动态显像作为一种简单创伤小的检查手段，对确定有无脑脊液鼻漏和确定具体漏口部位有重要作用。

The CT and MRI manifestations of pachygyria and agyria are presented with a review of the pathological features of the disorders and an evaluation of the diagnostic value of both imaging modalities.

结合巨脑回和无脑回畸形的病理特点，研究两种病变的 CT、MRI表现特征，以评价两种影像学检查方法该病变的诊断价值。

Pachygyria Agyria Tomography ; X ray computed Magnetic resonance imaging

巨脑回畸形；无脑回畸形； X射线电子计算机断层；磁共振成像

Cisterna longitudinal fissurae cerebri and cisterna lateralis fossae cerebri were increased significantly after the age of 50, and the changes of their sizes had pratical significance on judging the sizes of subaracnoid cistern and encephalatrophy.

50岁以后大脑纵裂池和大脑外侧窝池明显增大，这两个池的大小对脑池的大小和有无脑萎缩的判定有实用意义。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
