Rekürren mültipl intrakranial meninjiyom olgusu

Meninjionýlar gliomalardan sonra ikinci en sýk görülen tümörlerdir ve tüm santral sinir sistemi tümörlerinin yaklaþýk % 20’sini meydana getirirler. Mültipl meninjiomlar %5.9 ile %I0.5 arasýnda deðiþen bir insidaýýsa sahiptirler. Biz olgu bildirimizde, sað frontal meninjiom nedeniyle öpere edilmiþ olan 73 yaþýndaki bir kadýn hastayý sunduk. Operasyondan 8 yýl sonra hastada en az 6 yeni tiimör geliþmesi, bizi daha önce öpere edilen tümörden bir subaraknoid yayýlým olduðu kanýsýna yöneltti. Olgu sunumumuzda operasyonu takip eden yeni meninjiom geliþmesinin mekanizmasý, sýklýðý ve ortaya çýkýþýný tartýþtýk.

Recurrent multiple intracranial meningiomas

Meningiomas are the second most common tumors following glial tumors and account for approximately 20% of all central nervous system tumors. Multiple meningiomas have an incidence ranging between 5.9% and 10.5%. In our case report, we have presented a 73 year female patient who had been operated for a right frontal meningioma. After 8 years, she developed at least 6 more new tumors, which led us towards the supposition of a subarachnoid dissemination, resulting from the previously operated tumor. In our presentation, we have discussed the occurence, incidence and mechanisms of new meningioma development following operation.
