I recently posted that I was undergoing cervical and brain MRIs, with and without contrast.
Since my symptoms occur while I am upright, and subside when horizontal, I had suggested to my neurosurgeon that I have them done at a Stand-Up facility. He was very pleased with that idea (shouldn't it have been his??), and I just got the results yesterday.
Mine were negative for tachymeningeal enhancement, which according to my NS is the positive finding for a CSF leak. So I am back to square one.
However, I wanted to post this suggestion as an option to all my friends on this site who are suffering from a leak, or suspected one. Perhaps this test is an option, and may show significant findings and aid you in resolving your situation.
Good luck to all --
