Positional vomiting as the initial manifestation of Bruns syndrome due to cysticercosis in the fourth ventricle: a symptom reminiscent of an old disease

Intraventricular Taenia solium cysts presenting with Bruns syndrome and indications for emergent neurosurgery

Bruns syndrome is an unusual phenomenon, characterized by attacks of sudden and severe headache, vomiting, and vertigo, triggered by abrupt movement of the head. The presumptive cause of Bruns syndrome is a mobile deformable intraventricular mass leading to an episodic obstructive hydrocephalus. Intraventricular tumors have been associated with Bruns syndrome; however, few cases of intraventricular neurocysticercosis have been reported to present with Bruns syndrome. We report the first series of fourth ventricular neurocysticercosis presenting with Bruns syndrome in the United States and review the other published cases where surgery was indicated.
