Question Regarding Results of MRI

I recently had an MRI of brain. A doctor detected tremors in my speech and a Neurologist suggested the MRI.
The MRI showed a shaded white area. Doctor recommended a spinal tap and stated that this could be "Potentially indicative of anything from an auto immune deficiency to Lymes disease.

Any comment or discussion. Thank you for your interest

I end up in the hospital after having my done.  You may or may not have in problems after the procedure.  I was just one of the unlucky ones.  Good luck.
