Anomalie cerebellari fetali: confronto tra ecografia e risonanza magnetica prenatale e follow up a distanza

Cerebellar malformation are increasingly diagnosed in utero. To assess the effectiveness of ultrasound and fetal magnetic resonance in the antenatal prediction of long term neurodevelopmental delay.
STUDY DESIGN: We collected 105 cases of cerebellum malformation in the period 2000-2010 in Bologna and Bari University. Classification included cystic anomalies of posterior fossa and cerebellar hypoplasia.
RESULTS: The greater group included Blake’s pouch cysts and mega cisterna magna cases (58/105). These cases seemed to have a good prognosis with a good outcome both in association with other anomalies and isolated. In cases of Dandy Walker malformation, vermis hypoplasia and cerebellum hypoplasia there were few survivors, so it was so difficult to outline some conclusion for child outcome. Despite great neuroimaging advances, in our study, ultrasound and MR reached a similar sensitivity (62-63%) for the diagnosis of posterior fossa anomalies, but the number of MR was lower compared with ultrasonography.
CONCLUSION: Ultrasonography remains the screening method of choice for evaluation of cerebellum anatomy but probably MR imaging can improve some details expecially in the third trimester. Despite the data on Dandy Walker, vermis hypoplasia and cerebellum hypoplasia were conflicting and uncertain, for Blake and mega cisterna magna we can considered a rather good outcome.
