mri results

I apolegize in advance for the long post. here is a small background on myself. after my first son was born 18 years ago I had trouble with my hands and arms going numb and tingly, this only lasted a few weeks and went away so I did nothing about it. a couple of years ago I started feeling tired all the time and again had trouble with my hands and feet falling asleep alot. I am a hairdresser and left work oneday and my left leg felt real heavy, that scared me. I am a single mother of 3 teenage boys and thought my gp would just tell me I needed to slow down and start takeing better care of myself. Instead he sent for a mri. these were the results.
Findings: Flaair images, there are scattered high signal lesions seen in the previntricular white matter. the largest in the left temporal region at 9x5mm. also increased signal seen in the periventricular whit matter in the frontal, pareietal, and occipital lobes. 6x5mm. subcortical white matter lesion is seen in the posterior left frontaol lobe.faint small high signal lesions are also seen in the periventricular white matter.
Impression: scattered high signal flair lesions are seen in the white matter consistant with demyelinating disease.

first neuro dx. on these results and neuro exam, symptoms.
2nd mri: different Imaging location.
findings: there is no interval change in the mr appearance of several scattered flair hyperintense supratentorial lesions predominantly in the periventricular white matter also involving the centrum semiovale. no lesions are  recognized.
conclusion: Essentially stable-appearing mr of the brain with dominant findings reperesenting multifocal bilateral predominantly supratentorial flair hyperintence lesions; differential diagnosis would favor a demyelinating process such as multiple sclerosis.

2nd neuro says he dosnt know if would have dx. me yet because my spinal tap came back neg. but he is treating me anyways because I already have a dx. he sent me to his guy for my 3rd mri and these at\re the results. all of these within a year.
findings:Scattered amall foci of t2 signal are present in the cerebral white matter bilaterally. the largest of these are in the left posterior frontal operculum and in the left temporal white matter. measuring 3 to 4 mm. A total of 8 lesions are seen. Hazy white matter change is present around the posterior ventricles.
Impression: most probably these findings are secondary to ms. there is nothing absolutely typical about them except for the fact they are all in the white matter.

I am very confused because my new neuro keeps saying the lesions are not were ms lesions are normally located but he wants me to continue my treatment.
could you please help me understan what the 3rd mri meant by secondary to ms on the impression.
thank you so much for your time.

All MRIs done pointed to the impression of a demyelinating disease with the last two attributing the white matter lesions as secondary to multiple sclerosis (MS). Although the spinal tap revealed negative findings, this does not rule out the presence of MS.  Your neurologist probably based his decision to continue treatment on the overall clinical picture (MRIs + symptoms) as early treatment of MS has been found to be of significant benefit.  I would be advisable to continually monitor you condition by regular consults with your neurologist.

just wondering what the secondary to ms comment on the 3rd mri Imprssion is suppose to mean.
thank you.

It just means that the interpreter of the MRI believes that the MRI findings are most probably due to MS (multiple sclerosis).
