Neurofibroma

Healthcare providers typically use a physical examination to diagnose neurofibromas. They might also use the following imaging tests:

• Computed tomography (CT) scan and magnetic resonance imaging (MRI): Healthcare providers use these tests to find very small tumors. They may also use them to find out where a tumor is located and to identify any nearby tissues or organs that could be affected by surgery.
• Positron emission tomography (PET) scan: Healthcare providers use this test to see if a tumor is benign (noncancerous) or cancerous (malignant).
