Ewing Sarcoma Symptoms and Diagnosis

Symptoms of Ewing Sarcoma

The following are the most common symptoms of Ewing sarcoma. However, each child may experience symptoms differently. Symptoms may include, but are not limited, to the following:

  • Pain around the site of the tumor
  • Swelling and/or redness around the site of the tumor
  • Fever
  • Weight loss, decreased appetite
  • Fatigue
  • Paralysis and/or incontinence (if the tumor is in the spinal region)
  • Symptoms related to nerve compression from tumor (e.g., numbness, tingling, paralysis, etc.)

The symptoms of Ewing sarcoma may resemble other conditions or medical problems. Always consult your child's physician for a diagnosis.

How Ewing Sarcoma is Diagnosed

In addition to a complete medical history and physical examination of your child, diagnostic procedures for Ewing sarcoma may include:

  • Multiple imaging studies, such as:
    • X-rays - a diagnostic test which uses invisible electromagnetic energy beams to produce images of internal tissues, bones, and organs onto film.
    • Bone scans - a nuclear imaging method to evaluate any degenerative and/or arthritic changes in the joints; to detect bone diseases and tumors; to determine the cause of bone pain or inflammation. This test is to rule out any infection or fractures.
    • 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. This test is done to rule out any associated abnormalities of the spinal cord and nerves.
    • Computed 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.
  • Blood tests (including blood chemistries)
  • Biopsy of the tumor - a procedure in which tissue samples are removed (with a needle or during surgery) from the body for examination under a microscope; to determine if cancer or other abnormal cells are present; to remove tissue from the affected bone.
  • Bone marrow aspiration and/or biopsy - a procedure that involves taking a small amount of bone marrow fluid (aspiration) and/or solid bone marrow tissue (called a core biopsy), usually from the hip bones, to be examined for the number, size, and maturity of blood cells and/or abnormal cells.

Ewing sarcoma is difficult to distinguish from other similar tumors. Diagnosis is often made by excluding all other common solid tumors, and by the use of genetic studies.
