title: Prenatal imaging of congenital cerebral primitive neuroectodermal tumor.
abstract: A case of fetal brain tumor, which appeared after 32 weeks' gestation, is presented. Prenatal ultrasonography and magnetic resonance imaging demonstrated a large heterogeneous mass in the right supratentorial region and left enlarged ventricle. A male fetus weighing 2,616 g was delivered at 34 weeks' gestation by cesarean section and died on the 37th day of life due to rapid growth of the tumor. Following autopsy, the pathohistological examination revealed primitive neuroectodermal tumor. Magnetic resonance imaging in the prenatal management of the congenital brain tumor is efficient in evaluating the expansion and margin of the tumor and intratumoral bleeding, which are not demonstrated by ultrasonography.
