Objective: to reveal brain electrophysiological features by monitoring of AEEG before and after intracranialmass lesion surgery.
前言：目的：通过A EEG监测，了解颅内占位性疾病手术前后的脑机能变化特点。

As with other intracranial meningiomas, preoperative embolization may be efficacious in limiting blood loss, and may even produce a reduction in size of the mass before surgery.
与其他的颅内脑膜瘤一样，术前栓塞可以有效的减少出血，甚至可以使肿瘤缩小。

The malformations vary greatly in size and location, and produce symptoms through rupture (see also INTRACRANIAL HEMORRHAGES), mass effect, and vascular steal effect.
