What is Ill-defined hyperintensities?

[lexus01]

I just recently had an MRI of the brain, cervical & lumbar spine.  My report is as follows:  There are tiny hyperintensities at the frontal subcortical white matter and at the right parietal white matter.  Ill-defined hyperintensities at the posterior parietal white matter on both sides.  These are not typical for demyelination but in the appropriate clinical setting, cannot be entirely excluded.  Questionable hyperintensity at the right side of the pons.  

Final Impression: Tiny hyperintensities at the frontal subcortical white matter, right pariel white matter and ill-defined hyperintensities at the posterior parietal white matter.  These are nonspecific.  In the appropriate clinical setting, demyelination is not excluded. Differential diagnosis may include Lyme's Disease.  Prominent lymph nodes at the neck.

Ok...can a professional please explain this to me.  This is driving me nuts.  Initially they were saying it was MS, now a possibility of Lymes disease.   I am so confused.

Thank you so much.  I can rest better tonight.

You have some ill-defined intensified areas in your brain. These are not specific to any disease. You can only relate them if you have symptoms of any disease, you cannot diagnose anything with this report.
You have to sit with your neurologist and correlate the report with your symptoms. You have to go disease by disease and see if your suffering form Lyme's disease etc.
You have prominent lymph nodes in the neck, which can be due to any infection also.
Take care and visit your neurologist for the best interpretation with your symtoms.
