Help in understanding MRI results - multiple sclerosis?

I have already been dx'd with MS 8 years ago - this is an updated MRI. My neuro will not be available until next month. If anyone can help me understand what these new results mean I would truly appreciate it.

Here is what the report says:

"The study demostrates a few foci of high signal seen in the periventricular white matter, particularly along the posterior (isn't that my bum?) aspect of the lateral ventricle on the right. There are a few foci of increased signal seen in the body of the corpus callosum on the saggital proton density images. A few scattered subcortical white matter foci of high signal are noted. There is no diffusion abnormality and one of these abnormal areas show enhancement. The cerebellar tonsils (I know I had those removed are low-lying but do not appear to be ectopic. The orbits appear normal. A polyp/cyst is seen in the left maxillary sinus."

It does say at the end that the impressions are:

Foci of abnormal signal consistent with history of MS

Sorry - the thing about my "bum" was a joke :-) I realize this was a brain scan. What I'm trying to do is find someone that can really tell me what the results mean - I have already been dx'd with MS years ago.

Thefindings are that the MRI is consistent with MS as opposed to something else causing symptoms, either on its own or in combination with the MS.

The MRI also helps identify, describe, and in some instances date lesions in the brain (plaques).

posterior doesn't mean bum. All of the finds are in your brain. Just basically means that MS is found and a cyst is on your left sinus.
