title: A prenatal diagnosed case of primitive neuroectodermal tumor.
abstract: Congenital brain tumors presenting in the first year of life account for 1.4-8.5% of all childhood brain tumors. Only 18% of congenital brain tumors are diagnosed before or at delivery. Primitive neuroectodermal tumor (PNET) is a highly malignant, small, blue-cell tumor which is characterized by early recurrence, metastasis, and high mortality. It makes up 13% of all fetal and neonatal brain tumors. Prenatal diagnosis of PNET or other congenital brain tumors is important because the presence of tumors may alter the time and mode of delivery and postnatal care planning. A prenatal case of PNET is described that was diagnosed with ultrasonography and magnetic resonance imaging; the case was confirmed histopathologically at postmortem examination.
