What is a cervical teratoma?

A cervical teratoma is a large tumor that develops in the neck of a baby. These masses are an extremely rare form of a germ cell tumor and they are usually benign (non-cancerous).

The main concern with a cervical teratoma is obstruction of the baby's airway and esophagus, resulting in the accumulation of fluid that can affect growth and even result in preterm delivery.

At the Colorado Fetal Care Center, we work with families who've recently found out their baby has a cervical teratoma. From your first visit with our fetal experts to the day you deliver your baby, we'll use our advanced diagnostics and state-of-the-art facility to provide the best treatment in the region.

What causes cervical teratomas?

There are no known genetic connections to the formation of cervical teratomas. While they're the second most common form of fetal neck mass, there are only 150 cases reported.

Are there any complications of cervical teratomas?

Cervical teratomas can complicate a baby's development by blocking or narrowing his or her airway. The tumor can also compress the esophagus, making it difficult or impossible for your baby to swallow amniotic fluid, which can lead to polyhydramnios, or excess fluid in the amniotic sac. This, in turn, may lead to preterm delivery.

Cervical teratomas are equally dangerous after birth, since the obstruction of the airway may prevent the baby from breathing or delay the ability to secure the airway at birth. As a result, it's important to develop a delivery treatment plan soon after receiving a cervical teratoma diagnosis.
