[Self migrating intracranial bullets].

Area of Science:

• Neurology
• Neurosurgery
• Radiology

Background:

• Intracerebral and intraventricular bullets pose unique challenges due to potential migration.
• Understanding bullet dynamics within the brain is crucial for patient management.

Purpose of the Study:

• To report cases of bullet migration into the lateral ventricles.
• To review literature on factors influencing intracerebral bullet migration.
• To recommend imaging protocols for surgical removal of intracerebral bullets.

Main Methods:

• Case report of two patients with migrating intracranial bullets.
• Literature review on spontaneous migration of intracerebral bullets.
• Analysis of factors contributing to bullet mobility within brain tissue.

Main Results:

• Observed free movement of bullets within the lateral ventricles, influenced by gravity.
• Literature suggests cerebral softness and bullet specific gravity facilitate migration.
• X-rays are recommended post-surgery to confirm bullet removal.

Conclusions:

• Bullet migration within the brain is a recognized phenomenon.
• Cerebral tissue properties and bullet characteristics influence migration.
• Post-operative imaging is essential for intraventricular bullet removal confirmation.
