Neurocysticercosis of 4 th Ventricle-A Rare Site Encountered with Rare

Neurocysticercosis (NCC) is the commonest parasitosis of the Central Nervous System (CNS), endemic in developing countries and also seen in developed nations. The parasite usually invades the brain parenchyma and the patients present with a variety of neurological manifestations, mostly seizures and neural deficits. But we present a case of a 16 years old boy who presented with occipital headache, vomiting and difficulty in walking. CT scan and MRI showed a cystic mass lesion in the 4th ventricle causing obstructive hydrocephalus. Histopathological examination confirmed it to be neurocysticercosis. We present this case due to its rare site and unusual presentation. This case highlights the importance of careful interpretation of head CT scans in context of presentations of headache and other nurological deficit in a susceptible population.
