Teratoma

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.
