Migrating Souvenir Bullet: The Management Dilemma.

The cranio-cerebral trauma following gunshot injuries has high mortality and morbidity, with 66% to 90% victims dying before reaching hospital and only half of those treated in hospital surviving. However, in case of most salvageable patients, the question which poses dilemma to treating physicians is the decision as to when and why remove the retained missile. A 21-year-old man was observing a gunfight in the street from his balcony. Suddenly something struck his forehead and there was a small amount of bleeding toward the medial end of his left eyebrow. He had moderate headache and dizziness. Because of nonresolution of headache over seven days he was hospitalized and underwent X ray of the skull and CT of the head, which showed a retained metallic bullet in left inferior parieto-occipital region without any significant hemorrhage. As there was no neurological deficit or meningeal signs, he was managed conservatively. His symptoms improved gradually within next week and he was discharged home. His most recent follow-up was 28 months since injury and imaging showed migration of the bullet to the right inferior temporal region. As he was completely asymptomatic throughout, no intervention was offered. However, long-term follow-up for potential complications of migration, hydrocephalus, and abscess formation is advisable.
