Neurocysticercosis of the third ventricle: illustrative case

Abstract

BACKGROUND Neurocysticercosis is a parasitic infection of the central nervous system. Cysts located in the ventricles, intraventricular neurocysticercosis (IVNCC), can cause symptoms of increased intracranial pressure and, if untreated, can be fatal. Neuroendoscopic removal of IVNCC is recommended as the first-line treatment. OBSERVATIONS The authors present the case of a healthy 30-year-old male originally from Mexico who presented with headaches and vomiting. He was found to have a cyst in the third ventricle on imaging, consistent with IVNCC. The authors successfully performed neuroendoscopic surgery with removal of the cyst en bloc. LESSONS A multidisciplinary team of neurosurgery and infectious disease specialists is recommended for successful management of patients with IVNCC. These patients typically require neuroendoscopic surgical removal for definitive treatment. In this case, the authors show surgery resulted in an effective cure without the need for antiparasitic medication and excellent long-term outcomes.
