The tumor board is meeting right now, and we expect to hear back from them sometime after 2:30. I'll put up a quick post with high-level results as soon as we know something, and I'll elaborate later.

If we go with the assumption that the tumor is craniopharyngioma, everything I've been reading seems pretty encouraging. Here's an article from the Cancer Center at Johns Hopkins: http://www.childhoodbraintumor.org/Craniopharyngiomav1.pdf
