And that mass effect increases the intracranial pressure.

占位效应会升高颅内压。

In addition to intracranial bleeds, other causes of focal mass effects are tumors and abscesses.

除了颅内出血外，局部占位效应的原因还可能为颅内肿瘤或脓肿。

Diffuse mass effects are caused by generalized cerebral edema, which is an excessive buildup of fluid throughout the brain tissue.

弥散性占位效应的原因可能是广泛性大脑水肿（全脑水肿），即整个脑组织中液体的过度积聚。

Depending on the size and location of the mass effect, there's a possibility of brain herniations.

占位效应的大小和类型决定了脑疝发生的可能性。

There were no lesions and no mass effect that we could see.

我们找不出损伤和大量反应.

As the artery bleeds, the blood starts to pool, and that leads to what's called a mass effect within the skull.

动脉出血导致血液积聚，会导致颅内占位效应。

In order to confirm the presence of a mass effect that may be causing increased intracranial pressure, medical imaging such as CT or MRI can be used.

为了确诊是否有颅内占位效应可能导致的颅内压增高，可行影像学检查，如CT或MRI。

So, let's say there's a focal mass effect on the right side of the skull, which increases intracranial pressure and squeezes the uncus down onto the brainstem.

假设在颅骨右侧有一局部占位效应，导致了颅内压升高，且将颞叶钩回推向脑干。

Eventually, this injury of the left cerebral peduncle will result in weakness on the same side of the body as the side of the focal mass effect, also called ipsilateral weakness.

最终，左侧大脑脚的损伤会导致颅内占位同侧（右侧）的肌肉无力，即同侧偏瘫。

So, brain herniation can be caused by either a focal mass effect, like the arterial bleed, or a diffuse mass effect, depending on whether the problem is in one area or involves the entire brain.

脑疝的病因可能是由于局部的占位效应，比如说动脉出血；或者可能是弥漫性占位效应，即不只是局部大脑，而是整个大脑都受到影响。

It can cause problems, mostly due to mass effect because it starts putting on pressure on different areas of your brain, actually even pulling away blood circulation and bringing circulation to itself.

它可能会引起问题， 主要是由于质量效应， 因为它开始对大脑的不同区域施加压力，实际上甚至会拉动血液循环并恢复自身循环。

Most of the time, the signs and symptoms of Pancoast tumors result from the tumor creating local inflammation and swelling and pushing up against nearby nerves or blood vessels – which disrupts their function; a phenomenon known as mass effect.

大多数时候，肺上沟瘤的症状和体征是由于肿瘤形成局部炎症和水肿向上压迫邻近的神经或血管，导致其功能紊乱；该现象被称为“占位效应”。
