If I had a dollar for every time I found a foot in a newborn baby's brain...

... I wouldn't be working here any more, let me put it that way.

Dr. Paul Grabb said he operated on Sam Esquibel at Memorial Hospital for Children after an MRI showed a tumor on the newborn's brain. Sam was 3 days old and otherwise healthy.

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 breech 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."

Grabb isn't sure what caused the growth but says it may have been a type of congenital brain tumor. However, such tumors usually are less complex than a foot or hand, he said.

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.

Tumors are usually less complex than a foot or hand?

You mean, they're not always "less complex" than perfectly-formed human limbs?
