OBJECTIVE
To describe the cases of 2 fetuses with aneurysms of the vein of Galen diagnosed prenatally.
METHODS
The techniques used were conventional sonography, three-dimensional sonography, and ultrafast magnetic resonance imaging. On the basis of these imaging modalities, prognostic factors, such as drainage and secondary damage, were assessed.
RESULTS
The first fetus had good prognostic indices, and embolization after birth was successful. According to the prognostic factors, a poor neonatal outcome was predicted for the second fetus. The neonate died soon after birth.
CONCLUSIONS
Conventional sonography, color Doppler imaging, and magnetic resonance imaging appeared to be useful diagnostic tools. The prognostic factors can be useful in counseling patients and providing the best possible care after birth.
