Cephalad migration of an intradural bullet: a case report and review of the literature

Retained intradural bullets are rare and may migrate within the thecal sac, potentially causing neurological deficits and creating diagnostic and surgical challenges. Most reported cases describe caudal migration. This case highlights a 19-year-old man who experienced preoperative cephalad migration of an intradural bullet following a gunshot injury to the lower back. Furthermore, we review previously reported cases of migratory spinal bullets, including treatment modalities and neurological outcomes.
