Hi Markinidaho

I had a normal MRI for the pituitary in which someone noticed the "missing artery." There is a sort of pulse on the right side. The neurologist ordered an MRA which I'll have this Monday. He wants to see if it was never there or was damaged. If it was, it was probably when I was 11 months old and I went out of my crib onto my head and fractured my skull. The neurologist also ordered a thorough sleep study again since I have a history of central apnea, and a neuropsych exam. There is evidence that the left artery is somewhat bigger, probably to compensate. The guy said that if you are born with this, it's "no big deal." Typical.
