Kistik menenjiyomlar: üç olgu sunumu

Cystic meningiomas: report of three cases

Journal Name:

Publication Year:

Abstract (2. Language): 
Cystic meningioma is rare and accounts for 1.6 to 10% of all types of meningioma. Recognition of the diagnostic features of cystic meningiomas is important, because they may be difficult to differentiate from glial or metastatic tumors with cystic or necrotic changes, neuroblastoma, or hemangioblastoma. Different types of cystic meningiomas have been reported by various authors. We detected type 1 cysts in our first and third cases and a type 2 cyst in the second case according to the Nauta classification. Intratumoral cysts may result from cystic degeneration and ischemic necrosis or hemorrhage within the tumor and may be due to a secretory function of the tumor. Here we report three cases of cystic meningiomas and discuss the characteristics of these lesions with the studies found on Pubmed search
Abstract (Original Language): 
Kistik menenjiyom nadirdir ve tüm menenjiyomların %1.6 ile %10’unu oluş- turur. Kistik menenjiyomların tanısal özelliklerinin bilinmesi önemlidir, çünkü kistik ya da nekrotik değişikliklerle olan glial veya metastatik tümörleri, nö- roblastom ya da hemanjiyoblastomlardan ayırt etmek zor olabilir. Çeşitli yazarlar kistik menenjiyomların farklı tiplerini tanımlamışlardır. Nauta sınıflandırmasına göre, birinci ve üçüncü olgularımızda tip 1 kist ve ikinci olguda tip 2 kist tespit ettik. İntratümöral kistler, tümör içerisinde kistik dejenerasyon ve iskemik nekroz veya kanama sonucu oluşabilir ve tümörün bir salgı fonksiyonu sonucu da olabilir. Burada kistik menenjiyomlu üç olgu sunulmuş ve bu lezyonların özellikleri Pubmed araması sonucu bulunan araştırmalarla karşılaştırarak tartışılmıştır.
