Background:
Hydrocephalus caused by an intraventricular bullet is a rare event. We report a case of endoscopic removal of an intraventricular bullet.
Case Description:
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.
Conclusions:
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.
