Brun's syndrome is caused by a mobile deformable intraventricular mass leading to an episodic obstructive hydrocephalus resulting from an intermittent or positional CSF obstruction with elevation of intracranial pressure due to the ball valve mechanism. Treatment is mainly surgical, preferably by the neuroendoscopic technique as it has an advantage of performing septostomies and third ventriculostomies in addition to cyst removal, making this procedure practical for most cases of ventricular cysticercosis even in emergencies.
