Graphic Content: Picture of little boy that has four-inch-deep crack across his skull that’s getting bigger every week

Pheaktra Pov was born with the defect after doctors warned his mother, Srey, 40, when she was seven-months pregnant that her baby had a 'problem with his head.'

The youngster had a small crevice on the top of his skull but doctors were baffled and sent them home without any further treatment for the child.

Shockingly, the hole in his head has continued to get deeper and wider - now stretching from his forehead to the base of his skull on the back of his head.

Doctors told Srey that there is nothing they can do but Pheaktra’s grandmother Thorn Hong , 67, is determined to find a cure, no matter how expensive.

When he was five-years-old it seemed like there was water inside his head and it was swelling and getting bigger.

"I get about $10 to $25 a week from people at the Angkor Watt temple when I go on a Friday, Saturday and Sunday."

Local charities supply free medicine to Pheaktra but it is to prevent seizures and has no effect on the bizarre crack in his head." His mother said.
