I had a MRI on my knee yesterday. My doctor called and said “knee MRI shows mass on spine” and said I needed to see a specific orthopedic surgeon for a consultation next week. I looked up this surgeon and he specializes in orthopedic oncology. I don’t understand what the “on spine” means, since the MRI was only on my knee? The doctor also said they couldn’t tell what the mass was from the MRI. What are your thoughts?
