When Hemorrhage Hides a Fetal Brain Tumor, Importance of Fetal Autopsy Open
We present two types of FBT for which diagnostic orientation was initially erroneous because of the challenging antenatal diagnosis of FBT. Autopsy enabled to rectify the initial antenatal diagnosis and establish the FBT phenotypic profile.
