Σύνδρομο Dandy-Walker: Προγεννητική υπερηχογραφική ανίχνευση κατά το δεύτερο τρίμηνο της κύησης

Dandy-Walker syndrome is a rare inborn intracranial malformation consisting of partial or complete agenesis of the cerebellar vermis, an enlarged posterior fossa and cystic dilatation of the 4th ventricle. We herein report a case of Dandy-Walker syndrome detected incidentally during an urgent fetal ultrasound scan due to vaginal bleeding at 22 weeks of gestation. The couple decided termination of pregnancy, after adequate genetic counseling. Detailed postmortem examination revealed correlation between prenatal ultrasound findings and histopathology. Ultrasound can be used as the method for close monitoring antenatally, especially when pregnancy termination is preferred. Although, neuropathological examination is required in order to confirm this syndromic entity. [ABSTRACT FROM AUTHOR]
