Abstract

The causes of fetal ventriculomegaly vary. Ventriculomegaly can be caused by not only obstruction of cerebrospinal flow tract but also brain maldevelopment or other reasons. Recent advanced imaging technology and approaching technique of transvaginal sonography have contributed to an accurate prenatal diagnosis and clearly revealed fetal intracranial condition. However, management of the condition and counseling of parents are still difficult, because the initial cause, absolute risk, and degree of resulting neurological deficit cannot be determined with confidence. Ventriculomegaly is evaluated according to atrial width > 10 mm and mild ventriculomegaly is defined as an atrial width of 10 to 15 mm. In ventriculomegaly cases, accurate detection of intracranial structure and additional abnormalities is required. Furthermore, ventriculomegaly may resolve spontaneously or progress during pregnancy. Therefore, detailed neuroscan by advanced imaging technology, detailed extra-CNS scan, longitudinal serial scan during pregnancy are mandatory for proper counseling and management. Longitudinal observation study of not only short-term but also long-term neurological prognosis will be required.
