This area is known as a Ghon focus.

这个区域又称之为冈式病灶。

TB also gets the nearby hilar lymph nodes, either carried over by immune cells through the lymph or by direct extension of the Ghon focus infection and causes caseation there as well.

TB也会进入到临近的肺门淋巴结，它不是被免疫细胞带到淋巴结内，就是直接扩散到冈式病灶里面，在其中产生酪化作用。

If and when a person's immune system becomes compromised like with AIDS or with aging, the Ghon focus can become reactivated and the infection can spread to either one or both upper lobes of the lungs.

当一个人的机体免疫力受损时，例如罹患AIDS或年纪变大，冈式病灶会重新活跃并且感染会扩散到一或多个上肺叶。
