Multiple meningiomas cause, the cause of multiple meningiomas is caused by what

multiple meningioma is what causes it?

(a) causes In addition to the merger

neurofibromatosis is considered to be related with cell genetics, in general, the cause of multiple meningiomas is not clear, postoperative recurrence of meningioma with multiple meningiomas can be used to explain the spread of tumor cells with the cerebrospinal fluid, but can not explain the multiple primary meningiomas, Borovich other observed 14 cases of cerebral convexity meningiomas, found on the dura around the tumor with scattered multiple lesions, lesions in the dural layer between these clusters beaded, any pathological type can appear in multiple meningiomas, the same patient may appear different pathological types of meningiomas.

(B) the pathogenesis

on the mechanism of multiple meningioma, the current theory of multiple lesions and single lesion theory of two types of theory that patients with multiple lesions in the same environment in vivo, thus tumors may also occur in many arachnoid cells; single lesions doctrine is off circulating tumor cells in cerebrospinal fluid or blood circulation by the spread and emergence of new tumors, histologically, multiple meningioma may be the same histological type, but also for the different pathological types.
