title: Spontaneous gun pellet migration in the brain.
abstract: Majority of airgun injuries in the Kingdom of Saudi Arabia are accidental and involve children and adolescents. Potentially lethal penetrating injuries to the head often result from airguns. Computed tomography (CT) is the imaging modality of choice to determine the location of the pellet, and any associated brain parenchymal damage or haematoma formation. CT is also useful in demonstrating the fracture at the entry site of the pellet and any bone fragment which may be propelled into the brain. Although there have been a few case reports of spontaneous migration of metallic foreign body within the brain in the world literature, this case highlight the speed with which it can occur, even in a patient on complete bed rest.
