How are teratomas diagnosed?

They can often be seen on prenatal ultrasound.

Other diagnostic procedures can include:

Biopsy- a sample of tissue removed from the tumor and examined under a microscope
Complete blood count (CBC)- a measurement of size, number, and maturity of different blood cells in a specific volume of blood
Additional blood tests - may include blood chemistries, evaluation of liver and kidney functions and genetic studies
Multiple imaging studies, including:
  • Computerized tomography scan (also called a CT or CAT scan) - A diagnostic imaging procedure that uses a combination of x-rays and computer technology to produce cross-sectional images (often called slices), both horizontally and vertically, of the body. A CT scan shows detailed images of any part of the body, including the bones, muscles, fat, and organs. CT scans are more detailed than general x-rays.
  • Magnetic resonance imaging (MRI) - A diagnostic procedure that uses a combination of large magnets, radiofrequencies, and a computer to produce detailed images of organs and structures within the body.
  • X-ray- A diagnostic test that uses invisible electromagnetic energy beams to produce images of internal tissues, bones and organs on film.
  • Ultrasound (also called sonography) - A diagnostic imaging technique which uses high-frequency sound waves and a computer to create images of blood vessels, tissues, and organs. Ultrasounds are used to view internal organs as they function, and to assess blood flow through various vessels.
Boston Children’s is so much more than a hospital—it’s a community of researchers, clinicians, administrators, support staff, innovators, teachers, patients and families, all working together to make the impossible possible. ”
