An extra-axial hemangioma mimicking a large prenatal brain tumor

Abstract

A rare case of a congenital brain tumor was diagnosed by sonography in a fetus at 37weeks' gestation. The ultrasound examination showed a large area of both increased echogenicity and echolucency in one hemisphere suggestive of brain tumor or hemorrhage. Extensive surgical removal of the tumor was performed and revealed an extremely rare histological type of hemangioma. We reported an interesting case of neonatal cavernous hemangioma, mimicking a large prenatal brain tumor and treated successively in neonatal period.
