Notwithstanding the ultrasonography has permitted description of fetal brain anomalies during the antenatal period, the imaging appearances of various congenital intracranial tumors still overlap. Subsequent prenatal MRI allows the confirmation of ultrasound findings and detection for other anomalies that may be present, in particular, intracranial tumor extension. It has been reported that more precise morphology could be provided by MRI at earlier stages of gestation, which makes earlier diagnosis and prompt initiation of treatment possible. Cassart et al noted that MRI was more sensitive than ultrasound for the detection of this heterogeneity. Although there are many advantages of MRI, it must be noted that fetal MRI does not replace ultrasound as a screening tool.
