~~AVID (Asymmetric Ventriculomegaly~~Asymmetric ventriculomegaly, ~~Interhemispheric~~interhemispheric cyst and ~~Dysgenesis~~dysgenesis of the corpus callosum (AVID) is a recently recognised triad of congenital cerebral anomalies.

Radiographic features

markedly asymmetric enlargement of the lateral ventricles may be the initial finding on routine fetal morphology ultrasound.
interhemispheric cyst
dysgenesis of the corpus callosum
absent cavum septum pellucidum
macrocephaly

Associations

Other congenital abnormalities may be present, including Dandy-Walker malformation, grey matter heterotopia or polymicrogyria.

PrognosisTreatment and prognosis

Variable, but generally severe neurologic and developmental delay.
