Here's the email I sent out to friends and family this afternoon:
Hello,I'll post updates here too.
I've just heard back from the doctor regarding the results of Talia's various tests from last week and unfortunately the news is not good. The MRI shows no problems. However, the skull X-ray shows premature fusion of several of the skull bones. I am taking Talia for a neurosurgery consultation next week. It's possible that they will decide the problem is not serious enough to justify intervention. But the normal thing to do in such cases is surgery, and, from the limited amount I've been able to find out from the internet, it is quite invasive and traumatic -- basically cutting the skull apart and screwing it back together, involving a multi-day hospital stay.
I'll keep you updated as I get more information. Thank you to everyone for your concern.
