Clinical diagnosis: Thanks for the question: optic neuritis is a clinical diagnosis. Sometimes the radiologist can see inflammation and enhancement on MRI with specialized sequences and small field of view imaging (did you get an orbit mri?). We do not always see the abnormality on mri. The MRI may also have been to look for other lesions that can be associated with optic neuritis. Treat the patient not the mri.

Depends. : Assuming that the study was done with contrast and included the orbits, the absence of a certain type of lesion indicates that the neuritis is less likely to be due to multiple sclerosis. It is possible that the other findings of ms have not developed yet also. Overall, it is better to have a normal MRI scan than an abnormal one.
