Purpose: Various studies have been published on the use of fetal magnetic resonance imaging MRI in the assessment of posterior fossa PF abnormalities. In this study, MRI results of fetal PF analysis in our center have been evaluated. Methods and Material: The fetal MRG cases that were referred to our department have been retrieved by database search retrospectively. Among 308 fetal MRI cases that were examined at second or third the fetuses with PF anomalies were recruited.Results: Of the 308 fetuses, 47 mean gestational age 25.2 weeks had PF abnormalities. The most common abnormalities were, mega cysterna magna 18 , Arnold-Chiari II malformation 12 , occipital encephalocele 6 , Dandy–Walker malformation 5 , arachnoid cyst 3 and others 3 respectively. Twenty-three fetuses were followed-up, 17 terminated, 7 fetuses were lost to follow-up.Conclusion: The increased use of fetal MRI in the assessment of PF is important in consulting the clinician and the families by demonstrating the associated anomalies and detecting the rarely observed findings

Amaç: Fetal manyetik rezonans görüntülemenin MRG posterior fossa PF anomalilerinde kullanımı konusunda farklı yayınlar mevcuttur. Bu çalışmada merkezimizde fetal PF anomalilerinin MRG ile değerlendirme sonuçları incelenmiştir. Purpose: Various studies have been published on the use of fetal magnetic resonance imaging MRI in the assessment of posterior fossa PF abnormalities. In this study, MRI results of fetal PF analysis in our center have been evaluated. Gereç ve Yöntem: Bölümümüze refere edilen fetal MRG olguları retrospektif olarak veri tabanı incelemesi ile çıkarıldı. İkinci ya da 3. trimesterde fetal MRG yapılmış toplam 308 olgu arasından fetal PF anomalisi tanısı olan hastalar tespit edildi. Bulgular: Toplam 308 olgunun 47’sinde ortalama gestasyonel yaş 25.2 hafta PF anomalisi tespit edildi. En sık görülen anomaliler sırasıyla, mega sisterna magna 18 , Arnold-Chiari II malformasyonu 12 , oksipital ensefalosel 6 , Dandy–Walker malformasyonu 5 , araknoid kist 3 ve diğer 3 olarak izlendi. Postnatal takip edilen 23, termine edilen 17, takipten çıkan 7 fetus oldu. Sonuç:Fetal MRG kullanımının PF değerlendirmesinde yaygınlaşması eşlik eden bulguların saptanması ve nadir görülen anomalilerin tespiti nedeniyle klinisyene yol göstermesi ve ailelerin bilgilendirilmesi açısından önemlidir.
