Mediastinal teratoma

Also known as: benign mediastinal teratoma, germ cell tumor, teratoma of the mediastinum, mediastinal chest mass

What is mediastinal teratoma?

A mediastinal teratoma is a large mass that grows in the area between the two lungs. It’s a birth defect that is often benign, or non-cancerous. In some babies, it does not cause any problems, but in others it can lead to breathing difficulties and other problems.

What causes mediastinal teratoma?

The reasons why a mediastinal teratoma occurs in some babies aren’t clear. It is a very rare birth defect.

What are the symptoms of mediastinal teratoma?

Symptoms of mediastinal teratoma will vary based on its size and location. In some cases, it causes no symptoms. Other times, it can impact breathing or the function of the heart to the point that it is life threatening.

What are mediastinal teratoma care options?

Surgery is often recommended to remove the teratoma. This can even occur while the baby is still in the mother’s womb if the problems are severe and life threatening.
