Unilateral borderline fetal ventriculomegaly as inherited anatomical variant depicted by fetal and maternal magnetic resonance imaging.

摘要

Fetal borderline ventriculomegaly presents a challenge to all ultrasound examiners in terms of both differential diagnosis and counseling. In addition to ruling out other extracerebral abnormalities and offering karyotyping, magnetic resonance imaging (MRI) of the fetal brain is nowadays commonly performed as part of the diagnostic work-up. In borderline ventriculomegaly MRI can provide information on associated structural anomalies, the presence of hemorrhage or leukomalacia and cortical abnormalities otherwise not detectable on ultrasound examination. We report on a case with fetal unilateral borderline ventriculomegaly in which the family history raised the suspicion of an inherited disorder without clinical significance as shown by parental MRI.
