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
- 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

vascular lesions: although some of these are not really tumors, congenital malformations that may present as tumor like masses
- hemangioma
- lymphangioma
