Cerebral ventriculomegaly
Pronunciation: ven-trik-yoo-low-MEG-ah-lee
Abnormal enlargement of the fetal brain ventricles that may indicate neurological abnormalities.
Full Definition
Cerebral ventriculomegaly refers to the abnormal dilatation of the fetal brain ventricles, typically defined as lateral ventricular width measuring 10mm or greater at the level of the atria. It can be classified as mild (10-12mm), moderate (13-15mm), or severe (>15mm). Ventriculomegaly may be isolated or associated with other structural anomalies, chromosomal abnormalities, or congenital infections. The condition requires detailed neuroanatomical assessment, genetic counseling, and may warrant fetal MRI for better characterization of brain structures and prognosis.
Usage
Usage note: Always specify the measurement and classification (mild, moderate, severe) of ventriculomegaly.
