title: Increased lead absorption and lead poisoning from a retained bullet.
abstract: A young man was found to have elevated blood lead and erythrocyte protoporphyrin levels seven years after he had been shot in the foot with a .22 caliber bullet. Although clearly evident in radiographs obtained at the time of the accident, the bullet had never been removed. Over the course of the intervening years the radiographic appearance of the projectile changed dramatically. The patient underwent a surgical debridement procedure with some resolution of his lead intoxication. This case was reviewed in the context of the literature describing the disposition of retained lead projectiles. Lead bullets or fragments lodged within joints are slowly disintegrated and, as absorption accelerates, predispose the patient to the risk of lead poisoning which may occur many years after the original incident. Prompt removal of any lead projectile entering a joint space is strongly recommended.
