Good grief, 200 documented cases and this is the first I've ever heard of such a thing. I have been cooped up too much, I need to get out from under my rock more. 

I have heard of this before.  Apparently some people may  be walking around with their absorbed twin now  and have no idea.

Question : What possessed the doctors to check to see if a newborn was pregnant?

I reread the original post, and I find that my last question and the article itself are somewhat at odds. I get that they weren't checking to see if the newborn was pregnant, but what caused them to find the "tumors" in the newborns abdomin ? Would they have been hard lumps that the doctor could press and feel on the child's stomach? I'm still sort of in a fog on this one. Plus, since this happened back in 2010, I would love for the article to give an update on how the child is doing today. Just a thought.

I am guessing that maybe the baby's abdomen was unusually large indicating something was wrong.

Thank you. I like the way you think and I appreciate your correction of my typo, it didn't look right no matter how I typed it but it looks absolutely correct when you spell out the word. (Wordsmith's worst nightmare, my own typos   ) *abdomen, I've got to remember that spelling.

I wish the article had gone into more detail but then in print, space is a commodity. (Why isn't there a spellcheck here?)
