Just curious...what did your friend decide to do?
Sounds typical. She should definitely get a second opinion.
I told her to seek a second opinion. They are pushing her to terminate the pregnancy.
From what I just read about it, cysts on the spine are uncommon while pregnant and are very serious. I'm not sure about a 1% survival rate, but the ones I read about (that it mentioned) are meningomyelocele which is fetal spina bifida or Sacrococcygeal teratoma. Both of these are much more common in females versus males. She definitely needs to talk to her doctor about these.
