MR revealed that disorders previously referred to as the Dandy-Walker malformation, the Dandy-Walker variant, and the mega-cisterna magna actually are not separate
The distribution of cisterna magna width is established according to gestational weeks and percentiles between 15-24 weeks are calculated. Relationship between cisterna magna width and the other parameters were assessed by regression analysis. Results: Mean values of cisterna magna width between 15-24 weeks were 3,41±0,82-6,58±1,24 mm
