title: Exencephaly: sonographic findings and radiologic-pathologic correlation.
abstract: Exencephaly is a rare precursor of anencephaly in which a large amount of brain tissue is present despite the absence of the calvaria. It was discovered together with hydramnios in a near-term fetus. Sonographic, angiographic, and pathologic findings are discussed.
