Endoscopic Removal of a Bullet That Migrated to the Third Ventricle Causing Hydrocephalus.

Abstract

Hydrocephalus caused by an intraventricular bullet is a rare event. We report a case of endoscopic removal of an intraventricular bullet. A 66-year-old man was admitted with a gunshot wound to the head after a suicide attempt. The bullet migrated from the frontal parenchyma to the third ventricle day 4 of admission. On day 21 of admission, the patient developed hydrocephalus with obstruction of the cerebral aqueduct. The bullet was accessed through an endoscopic third ventriculostomy and removed using an endoscope. Hydrocephalus may develop in patients with intraventricular foreign objects. When such objects must be removed, the endoscopic approach is a safe, efficient, and minimally invasive procedure. To our knowledge, this is the first case in the literature of foreign object removal from the ventricle via a transcortical endoscopic approach.
