How does a soft tissue sarcoma appear on an x-ray?

Rarely.: If you are talking about a plain, standard, old-fashioned x-ray, soft tissue sarcoma rarely appears because these types of x-rays are really designed to evaluate bones. Soft tissue sarcomas are usually fleshy and better evaluated with ct scans (a different kind of x-ray), or mri. Sarcoma that has spread to the lungs can be see on a plain chest x-ray thought.

It usually doesn't: You usually do not see a soft tissue sarcoma on x-ray. At most, you may see some "extra" soft tissue. A type of sarcoma, synovial sarcoma, may have soft tissue calcifications in it. But overall, MRI is the modality of choice for imaging a soft tissue sarcoma. After mri, you need a biopsy to prove that it is a sarcoma.

MRI scan best: The best imaging studies for soft tissue sarcomas are MRI scans. Sarcomas have a very distinctive appearance on MRI scans, usually almost diagnostic.
