Diagnosis

Imaging tests may include:

• X-rays
• Ultrasound
• Computerized tomography (CT) scan
• Magnetic resonance imaging (MRI)
• Positron emission tomography (PET)

To confirm a suspected solitary fibrous tumor, a doctor may remove a small piece of tissue for examination under a microscope (biopsy). An experienced pathologist can confirm the diagnosis and determine whether the tumor is cancerous.
