title: Spontaneous migration of a retained bullet within the brain: a case report.
abstract: Gunshot injury to the head is usually mortal, and spontaneous migration of a retained bullet is rare. We report the case of a 23-year-old man with a spontaneously migrated bullet within the brain. Cranial computerized tomography (CT) indicated that the bullet was lodged deeply in the left parietal region. The patient was conscious and had right homonymous hemianopsia. The bullet was close to the vital structures and deep-seated; therefore, surgical intervention was not considered. Two months after the injury, repeat CT revealed that the bullet had migrated posteriorly and caudally due to gravitational factors. Management of the retained bullet was controversial. Removal of a deep-seated bullet may cause additional neurological deficit, but migration of a retained bullet may cause damage to vital structures, producing significant neurological damage. We proposed that the bullet in the brain should be removed if it could be reasonably accessed without causing additional neurological damage.
