Purpose or Case Report: Congenital tumors represent only 1.5–2% of all pediatric tumors, with a prevalence of 1:12,500 to 1:27,500 live births. Tumors are considered congenital when detected during pregnancy or in the first 3 months of life (1). Nowadays, with more accessible prenatal care and fetal imaging, these tumors can be detected very early during fetal period. Some lesions are benign, while others carry high risk of morbidity and mortality postnatally. As a radiologist, it is important to be familiar with these tumors by recognizing their imaging features, imaging modality work up and differential diagnosis. Doing so, we contribute to a proper imaging evaluation, early diagnosis and management.

The objectives of this educational exhibit are:
-To describe the imaging features of some congenital tumors on different image modalities.
-To recognize and emphasize the key radiologic findings of each tumor and their differential diagnoses.
-To briefly review the literature, including etiology, epidemiology, cytopathology characteristics, diagnosis and treatment.

Pictorial cases from our Radiology Department will be used to describe the imaging features of the following entities:

1) Head/Neck:
● Atypical teratoid/rhabdoid tumor (ATRT)
● Cervical teratoma
● Hemangioma

2) Chest:
● Neuroblastoma
● Cardiac rhabdomyoma

3) Abdomen- Pelvis:
● Hepatic hemangioendothelioma
● Hepatic hemangioma
● Neuroblastoma
● Mesoblastic nephroma
● Sacrococcygeal teratoma

4) Soft tissues:
● Infantile fibrosarcoma

5) Systemic:
● Leukemia
