These last two, the arachnoid and pia maters, are the leptomeninges.

后两者，蛛网膜和软脑膜，合称柔脑膜。

More specifically, it refers to the inflammation of the two inner layers which are called the leptomeninges.

更具体地讲，它是指两个内层发生炎症（即所谓的柔脑膜）。

Now there are two routes that an infection take to reach the CSF and leptomeninges.

现在感染一般通过两个途径接触脑脊液和柔脑膜。

Between the leptomeninges there's the subarachnoid space, which houses cerebrospinal fluid, or CSF.

在柔脑膜（蛛网膜和软脑膜）之间是蛛网膜下腔空间，容纳脑脊髓液，或缩写为CSF。

The pia and arachnoid mater are also called leptomeninges.

软脑膜和蛛网膜也可以合称柔脑膜。

Meningitis is the inflammation of the leptomeninges, which remember are the inner two membranes around the brain and spinal cord.

脑膜炎是柔脑膜的炎症；记住，柔脑膜指的是内里的两层包围着大脑和脊髓的脑膜。

Between the leptomeninges, there's a subarachnoid space, which houses Cerebral Spinal Fluid, or CSF.

在这两层中间有蛛网膜下隙，其中含有脑脊液，简称CSF。

Meningitis is an inflammation of the leptomeninges, the inner two membranes that surround and protect both the brain and spinal cord.

脑膜炎是柔脑膜感染炎症，也就是内两层膜是围绕和保护大脑和脊髓的脑膜。

It normally starts when a foreign substance, oftentimes bacteria, makes its way inside the leptomeninges, either by by direct contact or hematogenous spread through the blood brain barrier.

它通常由于异物，有时是细菌，进入柔脑膜；可能是通过直接接触或透过血脑屏障进行血性传播。

For bacterial meningitis, It's common is to administer steroids and then antibiotics, to prevent massive injury to the leptomeninges from the inflammation caused as the antibiotics destroy the bacteria.

对于细菌性脑膜炎，利用类固醇后使用抗生素是常见的方法，目的是为了在当抗生素破坏细菌时防止炎症对柔脑膜产生大规模损伤。
