For those who would like to see what a fetus in fetu looks like...
Here's a photo of the man in India that had a partially developed fetus removed from his abdomen as well as the ABC News Fetus in Fetu Story.
This isn't the same fetus that was removed from the guy above, but it was the fetus involved in a similar case.Finally, an MRI showing a partially developed fetus inside a new born male. You can read the case report that was published in Radiology, a peer-reviewed medical journal.
Weird, but true.
