COLORADO SPRINGS, Colo. — 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.

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.

Sam's parents, Tiffnie and Manuel Esquibel, said their son is at home now but faces monthly *lo** tests to check for signs of cancer or regrowth, along with physical therapy to improve the use of his neck. But they say he has mostly recovered from the Oct. 3 surgery.

"You'd never know if he didn't have a scar there," Tiffnie Esquibel said.
