Choroid Plexus Papillomas (CPPs) are rare intracranial neoplasms especially in the third ventricle. The most common site of presentation of these lesions is in the fourth ventricle in adults and lateral ventricles in children. Third ventricular lesion is uncommon, limited to a few case reports. These highly vascular tumours retain the physiological function of choroid plexus and thus lead to overproduction of Cerebrospinal Fluid (CSF) besides obstructing the pathway resulting in hydrocephalus. CT and MRI are the investigations of choice and are diagnostic. Surgical management vary according to the site of tumour and aim is complete excision of tumour. We present an interesting report of a 5 months old infant who presented with symptoms of raised intracranial pressure whose CT revealed third ventricular CPP. After ventriculoperitoneal shunt, tumour was excised. Pathological examination revealed choroid plexus papilloma.
