I learned that the experts do NOT consider an empty sella a problem without a high reading with a lumbar puncture. I remember discussing this with the neurologist at Mayo. He said that 6% of “normals” will also display an empty or partially empty sella. I countered that perhaps they should reconsider, if I had EVERY SYMPTOM of high ICP along with that partially empty sella? (doesn’t that make sense? I mean, really…). I think you know from the book about our tendency to develop chronic leaks from lumbar punctures, so I wasn’t going to let them do that just to prove my point! Instead, my kids and I responded beautifully to Diamox. Although we no longer need Diamox, it was a life-saver for a couple of years! 🙂
