Prenatal teratom tanısı almış anterior ve posterior yerleşimli meningomyelosel olgusu

Spinabifida, embriyonik nöral tüpün kapanma defektinin neden olduğu, spinal kord ve vertebranın malformasyonları için kullanılan ortak bir terimdir. Meningomyelosel ise spinal kord ve spinal sinir köklerinin birlikte açıkta kalması ile meydana gelen ve spina bifidanın % 90’ını oluşturan bir malformasyondur. Bu malformasyonların % 90‘ından fazlası multifaktöriyel kalıtımla oluşmaktadır. Hastaların kardeşlerinde benzer tanı ve hikâyelerinde ebeveyn akrabalığı olması hastalığın genetik kalıtımı olduğunu ortaya koymaktadır. Hastalığın tanısı ultrasonografi ile prenatal dönemde konulabilmektedir. Burada anne baba arasında akrabalık bulunmayan ve antenatal dönemde teratom düşünülen ancak postnatal olarak anteroposterior yerleşimli meningomyelosel tanısı alan bir yenidoğan olgu sunulmuştur. 

A case of anterior-posterior meningomyelocele which was diagnosed falsely as teratoma during antenatal period

Spina bifida, is a common term for malformations of spinal cord and vertebra caused by in complete fusion of the embryonic neural tube.   Meningomyelocele is a malformation that consists 90% of spina bifida and is caused by opening of the spinal cord and spinal nevre roots together. More than 90% of the malformations have multifactorial heredity. Because siblings of the se patients have also similar diagnoses and their parents are relative to each others, it supports a heredity origin of the disease. It can be diagnosed prenatally by the ultrasound. In this paper, we present a case, who born to non-consanguineo us parents, and it was thought as a case of teratoma, but postnatally diagnosed as anteroposterior meningomyelocele.
