Thrombosed Fetal Dural Sinus Malformation: Correlation Between Prenatal Ultrasound and Autopsy Findings.

INTRODUCTION: Dural sinus malformations, which are characterized by massively dilated dural sinuses, are one of the etiologies of an intracranial fetal cystic mass. Thrombi within these dural sinus malformations can develop while in-utero, and can be visualized by ultrasound in fetal life. Definitive postnatal diagnosis requires an autopsy. CASE REPORT: We report two thrombosed fetal dural sinus malformations which are prenatally suspected during the second trimester with ultrasonography and postnatally confirmed with autopsy.
CONCLUSION: Prenatal ultrasound images and fetal autopsy findings can be useful to establish the prenatal diagnosis of thrombosed dural sinus malformation.
