Pre- and Post- Natal Us and Mri Findings of Fetal Brain Lesions: A Pictorial Review

Abstract

The purpose of this exhibition is to demonstrate and compare pre- and post-natal US and MRI findings of various anomalies involving fetal brain. The contents of this exhibition will be variable neural tube defects, midline anomalies including agenesis of corpus callosum and Dandy-Walker continuum, lissencephaly, intracranial hemorrhage, dural arterior venous fistula, dural sinus thrombosis, variable intracranial cystic lesions and brain tumors. Various anomalies may occur in the fetal brain. US is not only the first line but also a confirmative study in many cases of fetal brain anomalies. MRI is increasingly being used to evaluate the fetal brain, and is a valuable complement to prenatal US. Almost fetal brain anomalies show specific imaging features and can be diagnosed on the prenatal US and MRI. The exact prenatal diagnosis and thorough postnatal work-up of fetal brain anomalies are important for the prenatal and postnatal managements.
