Understanding Sacrococcygeal Teratoma: Diagnosis, Treatment, and Prognosis for Newborns

When a baby is born with a large congenital tumor, such as a sacrococcygeal teratoma (SCT), the condition presents significant challenges for both the baby and medical professionals. One recent case, where a baby was born with a rare 4-pound tumor weighing nearly two-thirds of her body weight, highlights the complexities of treating such conditions. Sacrococcygeal teratoma, a rare tumor found at the base of a baby’s spine, is one of the most common types of congenital tumors, though it still affects only about 1 in 35,000 live births​(Children’s Health).

In this article, we’ll explore the nature of SCT, the diagnosis and surgical treatments involved, and what parents can expect regarding the prognosis for newborns born with these large tumors.

What is Sacrococcygeal Teratoma (SCT)?

A sacrococcygeal teratoma (SCT) is a tumor that develops at the base of the coccyx (tailbone) in a fetus. These tumors can vary greatly in size, sometimes growing to be quite large, as in the case of the baby born with a 4-pound tumor. While SCTs are benign in most cases, about 10% of these tumors are malignant​(Children’s Health) . Even when benign, the size and location of the tumor can cause significant complications.

Tailbone tumors in newborns, such as SCT, develop from germ cells and can contain a variety of tissues like hair, muscle, and bone. As the tumor grows, it can exert pressure on the baby’s internal organs, potentially causing other health issues. Early detection and treatment are crucial to minimizing these risks.

Diagnosing Fetal Tumors: How Early Can SCT Be Detected?

Prenatal diagnosis is key to identifying fetal tumors such as SCT early in pregnancy. Advances in imaging technology, such as ultrasound and MRI, now allow doctors to detect congenital tumors as early as the second trimester​(Children’s Health). Fetal tumor diagnosis is usually made through routine prenatal ultrasounds, where the presence of a mass near the baby’s tailbone becomes visible. The size of the tumor can vary, and doctors monitor its growth carefully throughout pregnancy.

Once a diagnosis is made, specialists will assess the tumor’s impact on the baby’s health, including risks to vital organs or circulation. In cases where the tumor is large, it may require close monitoring for signs of complications, such as fetal hydrops, a condition where excess fluid accumulates in the baby’s body due to the pressure the tumor exerts .

Fetal Surgery for Tumor Removal: An Option for Some

In extreme cases where the tumor’s growth endangers the baby’s health before birth, fetal surgery for tumor removal may be considered. Fetal surgery is a delicate procedure that involves partially delivering the baby, performing surgery to remove the tumor, and then returning the baby to the womb to continue developing until full term​(Children’s Health). This is considered a high-risk procedure, but it can be life-saving for babies with large congenital tumors like SCT.

More commonly, doctors may opt to monitor the tumor closely and schedule surgery shortly after birth. In cases like the baby born with a rare 4-pound tumor, surgery typically takes place within the first few days of life to remove the tailbone tumor and prevent further complications.

Teratoma Surgery: What Happens After Birth?

If the tumor is not removed during pregnancy, teratoma surgery is usually performed soon after birth. Pediatric tumor removal involves a team of specialists, including neonatologists, pediatric surgeons, and oncologists, who work together to ensure the best possible outcome. The goal is to remove the entire tumor while preserving as much normal tissue as possible​(Children’s Health).

In cases where the tumor is benign, surgery is typically curative, and the baby can recover without long-term health problems. However, in cases where the SCT is malignant or there are complications during surgery, additional treatments such as chemotherapy may be needed​(Children’s Health).

Prognosis: What is the Outlook for Babies with SCT?

The neonatal tumor prognosis for babies with SCT is generally positive, especially when the tumor is benign. The success of pediatric tumor removal surgery largely depends on the size of the tumor and the baby’s overall health. In cases where the tumor is diagnosed early and carefully monitored, most babies recover fully after surgery​(Children’s Health).

For babies with malignant tumors, the prognosis can vary depending on the tumor’s size, location, and response to treatment. Long-term follow-up care may be necessary to monitor for any recurrence or complications related to the tumor.

Factors Affecting Prognosis:

• Tumor size: Larger tumors can complicate surgery and affect nearby organs.
• Benign vs. malignant: Malignant tumors require additional treatments, such as chemotherapy, which may affect the prognosis.
• Early diagnosis: Tumors detected early in pregnancy are easier to monitor and treat, improving the outcome.

Hope for Babies Born with Rare Tumors

A diagnosis of sacrococcygeal teratoma (SCT) can be overwhelming for parents, but advances in prenatal diagnosis, surgical techniques, and postnatal care offer hope. While some tumors, like the rare 4-pound tumor seen in recent cases, can present significant challenges, most babies born with SCT can lead healthy lives after surgery.

The key to managing congenital tumors like SCT lies in early detection, careful monitoring, and timely surgical intervention. With the right medical team, babies born with SCT have a high chance of recovery and a bright future.
