Intraventricular migration of fourth ventricular neurocysticercosis: an unusual complication during endoscopic surgery

Abstract

A boy in his middle childhood presented with intermittent episodes of headache with vomiting for 6 months. Plain CT of the head and MRI of the brain revealed fourth ventricular cysticercal cyst with acute obstructive hydrocephalus. Endoscopic excision of the cyst was done along with endoscopic third ventriculostomy and septostomy with external ventricular drain placement. Although we were able to decompress the cysticercal cyst, unfortunately, the cyst got slipped from the grasper leaving the grasped cyst wall in the tooth of the grasper. Through this case report, we want to highlight that such a complication could also happen during neuroendoscopic cysticercal cyst removal and how we dealt with it. Our patient was discharged neurologically intact and was symptom free on follow-up.
