Although rare, a number of tumors may be diagnosed antenatally. These fetal tumors are a diverse and a unique group of conditions, and include:

• neuroblastoma: most common tumor overall
• teratomas
  • sacrococcygeal teratoma
  • head and neck teratoma/epignathus
  • mediastinal teratoma
  • intrapericardial teratoma
  • retroperitoneal teratoma: fetus in fetu
• intracranial fetal tumors
  • intracranial fetal teratoma: most common intracranial fetal tumor
  • fetal astrocytoma(s)
  • fetal choroid plexus papilloma ^6-7
  • fetal intracranial lipoma
• fetal cardiac tumors
  • cardiac rhabdomyoma: considered the commonest fetal cardiac tumor
  • cardiac fibroma: considered second commonest fetal cardiac tumor
  • cardiac teratoma: considered third commonest fetal cardiac tumor
    • fetal pericardial teratoma
• fetal soft tissue tumors
  • digital fibromatosis
  • fibromatosis
  • fibrous hamartoma
  • infantile fibrosarcoma: the most common fetal soft tissue malignancy
  • myofibromatosis-infantile myofibromatosis
  • rhabdomyosarcoma
  • PNET
  • rhabdoid tumor
• fetal hepatic tumors
  • infantile hemangioendothelioma
  • hepatic mesenchymal hamartoma
  • hepatoblastoma
  • metastases: fetal neuroblastoma and leukemia
• fetal renal tumors
  • mesoblastic nephroma: most common fetal renal tumor
  • Wilms tumor
  • rhabdoid tumor
• other fetal intraabdominal tumors
  • fetal neuroblastoma
• vascular lesions: although some of these are not really tumors, congenital malformations that may present as tumor like masses
  • hemangioma
  • lymphangioma
  • arteriovenous malformations, e.g. vein of Galen malformation
