Diagnosis of Sacrococcygeal Teratoma


Sacrococcygeal teratoma (SCT) is a rare tumor that develops at the base of the tailbone (coccyx) in infants. It is a type of germ cell tumor that contains tissues from different organs, such as skin, muscle, bone, and even organs like the liver or lungs. Early diagnosis of SCT is crucial for effective management and treatment. Medical professionals employ various diagnostic methods to identify and evaluate the presence of sacrococcygeal teratoma.



Physical Examination


During a physical examination, a healthcare provider will carefully examine the baby's lower back and pelvis. They will look for any visible signs of a mass or abnormal growth. The size, location, and characteristics of the tumor can often be determined through this initial assessment.



Imaging Tests


Ultrasound: Ultrasound is commonly used as the initial imaging modality for diagnosing sacrococcygeal teratoma. It uses sound waves to create images of the tumor and surrounding structures. Ultrasound can help determine the size, location, and internal composition of the tumor, as well as its blood supply.


Magnetic Resonance Imaging (MRI): In some cases, an MRI may be recommended to obtain more detailed images of the tumor. MRI uses powerful magnets and radio waves to create detailed cross-sectional images of the body. It can provide information about the extent of the tumor, its relationship with nearby structures, and help in surgical planning.



Alpha-Fetoprotein (AFP) Test


Alpha-fetoprotein (AFP) blood test: AFP is a protein produced by the developing fetus. In cases of sacrococcygeal teratoma, the tumor cells may release AFP into the bloodstream. Measuring AFP levels in the mother's blood during pregnancy or in the baby's blood after birth can help in the diagnosis and monitoring of SCT. Elevated AFP levels may indicate the presence of a sacrococcygeal teratoma.



Biopsy


In some cases, a biopsy may be performed to confirm the diagnosis of sacrococcygeal teratoma. During a biopsy, a small sample of tissue is taken from the tumor and examined under a microscope. This helps determine the type and nature of the tumor cells, providing valuable information for treatment planning.



Genetic Testing


In certain situations, genetic testing may be recommended to identify any underlying genetic abnormalities associated with sacrococcygeal teratoma. This can help in understanding the cause of the tumor and guide treatment decisions.



Conclusion


Diagnosing sacrococcygeal teratoma involves a combination of physical examination, imaging tests such as ultrasound and MRI, AFP blood test, biopsy, and genetic testing. These diagnostic methods help healthcare professionals determine the presence, characteristics, and extent of the tumor, enabling them to develop an appropriate treatment plan for the affected infant.

SCT is most often diagnosed while the newborn is still in utero with an ultrasound. Your doctor may refer you to get an MRI in addition to this once diagnosed. For toddlers or (in rare cases) adults with suspected SCT, it is diagnosed with an MRI. In blood work, elevated levels of AFP (alpha fetal proteins) are tumor markers and another way of diagnosing and monitoring the tumor.
There are 3 types of tumors classified by their relative extent inside and outside the body:
Altman type I — entirely outside, sometimes attached to the body only by a narrow stalk
Altman type II — mostly outside
Altman type III — mostly inside
Altman type IV — entirely inside; this is also known as a presacral teratoma or retrorectal teratoma
The type can change over time as the tumor grows, and is significant when managing of labor and delivery, the surgical approach, and further complications.
