Congenital cervical teratomas.

Congenital cervical teratomas are rare, representing 3% of teratomas in childhood. Although mostly benign, they are associated with a high mortality rate due to respiratory distress and require immediate surgical excision. The diagnosis is usually suggested on the physical examination. The imaging investigation is essential for the proper diagnosis and preoperative planning. We present the imaging characteristics of cervical teratomas identified in five neonates over a 10-year-period. The masses were surgically resected. Histopathology revealed the presence of congenital teratomas (three immature, two mature). Two neonates died soon after surgery, while the remaining were discharged from the hospital without symptoms.
