Abstract :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
