Well, they ran another CAT scan today, this one more thorough than the first. The results came back with the prognosis that Mom might need surgery, but for what we're not sure yet. The doctor will be in to see her first thing tomorrow morning, and we'll know then. If she *does* need surgery, it will take place at 3:15pm (EST).
Unfortunately, I'll be at work until 3pm so most likely won't be able to get here to post anything even though I'll have heard the results. So, if you're so led, pray for Mom throughout the day and especially around the 3 o'clock hour.
I'll update again tomorrow night.
