Foot on the Brain

Ew.

A pediatric neurosurgeon says a tumor he removed from the brain of a Colorado Springs infant contained a tiny foot and other partially formed body parts. ... Grabb said that while removing the growth, he discovered it contained a nearly perfect foot and the formation of another foot, a hand and a thigh.

"It looked like the breach delivery of a baby, coming out of the brain," Grabb said. "To find a perfectly formed structure (like this) is extremely unique, unusual, borderline unheard of."

...
The growth may also have been a case of "fetus in fetu" -- in which a fetal twin begins to form within another -- but such cases very rarely occur in the brain, Grabb said.
