Fourth ventricle neurocysticercosis presenting with Bruns' syndrome: A case report.

Background: Neurocysticercosis (NCC) is the most common helminthic infection of the central nervous system. We present a case of the fourth ventricle NCC that presented with Bruns' syndrome (with headaches worsened by head movements, gait ataxia, and vomiting) and the operative technique used for cyst removal.

Methods: A 39-year-old woman was admitted to the emergency department with moderate-to-severe headaches that got worse in the afternoon and were triggered by head movements, relieved on prone position, and were associated with gait ataxia and vomiting. A brain magnetic resonance imaging (MRI) showed a fourth ventricle cyst, with an eccentric enhancing nodule compatible with a larvae scolex and associated obstructive hydrocephalus. The patient was positioned prone and underwent a microsurgical resection of the cyst without rupture through a telovelar approach to the fourth ventricle. The postoperative MRI confirmed complete cyst removal and resolution of the hydrocephalus. At 12-month follow-up, the patient remains with no signs of disease recurrence.

Conclusions: In this report, we depict a case of intraventricular NCC successfully treated with a single surgery, allowing intact cyst removal and achieving effective hydrocephalus treatment with no need to resort to cerebrospinal fluid diversion techniques.
