1966 Forehead Grenade X-ray
While the origin of this x-ray is unknown, it has been speculated to be a relic from the Vietnam war.
The x-ray shows an intubated person with a hand grenade embedded in the forehead from 1966.
This photo is rumored to have appeared in an old x-ray training textbook with a caption stating the soldier in this x-ray had been walking behind another soldier who set off a mine. The resulting explosion blew the grenade off the webgear of the soldier who set off the mine and struck the soldier in the x-ray.
