Abstract
Neurocysticercosis is a parasitic infection of the central nervous system commonly caused by Taenia solium. Imaging with magnetic resonance imaging (MRI) is critical for diagnosis and follow-up of the infection. In this report, we present the case of a 44-year-old male with a history of chronic neurocysticercosis who presented with acute neurological symptoms. An initial MRI showed new obstructive hydrocephalus due to a cyst in the third ventricle. The patient underwent placement of an external ventricular drain to relieve the obstructing hydrocephalus. Follow-up imaging revealed interval migration of the cyst to the fourth ventricle. The cyst was removed surgically, and the patient recovered without any complications. This case emphasizes the importance of timely imaging for effective surgical planning of neurocysticercosis.
