Solitary Fibrous Tumors

Diagnosis

To help determine the best treatment options, doctors at Mayo Clinic combine the latest diagnostic techniques with experience in diagnosing solitary fibrous tumors. After taking a medical history and doing a physical exam, your doctor may recommend the following.

• Lab tests. Your doctor may order blood and urine tests.
• Imaging studies. Your doctor may order X-rays and other imaging techniques such as ultrasound, computerized tomography (CT) scan, magnetic resonance imaging (MRI) or positron emission tomography (PET). In tests that involve radiation, specialists carefully monitor doses to avoid the risk of radiation overexposure.
• Biopsy. To confirm a suspected solitary fibrous tumor, a doctor may remove a small piece of tissue for examination under a microscope (biopsy). A pathologist will determine whether the tumor is cancerous or not.
