此病为发源于颈静脉球的新生物,生长缓慢,富于血管,其组织结构稍属良性,但有局部破坏性,可以侵蚀岩骨,侵入中耳及乳突,累及第Ⅶ至第Ⅻ颅神经,亦可进一步扩展至颅内,表现如小脑脑桥角肿瘤,或向颅外扩展成为鼻咽部或颈上部肿块。远处转移较少见。 This disease is a new organism originating from the jugular bulb. It grows slowly and is rich in blood vessels. Its tissue structure is slightly benign, but it is locally destructive. It can erode the petrous bone and invade the middle ear and mastoid, involving the VII to the XII. The cranial nerves can also be further expanded into the brain, manifesting as cerebellar phalanx tumors, or expanding extracranially into nasopharyngeal or upper neck masses. Distant transfer is rare.
