Abstract

Choroid plexus tumors are rare intraventricular tumors. The common locations are the lateral ventricle in children and the fourth ventricle in adults. In adults, they are commonly located in and generally present before the age of 2 years. The main aim is to give a step by step approach with ruling out the differential diagnosis and reaching a diagnosis of a choroid plexus tumor. With the help of ultrasonography, computed tomography and magnetic resonance imaging sequences and ruling out the differentials in every step and reaching to a diagnosis of a choroid plexus tumor. Points to reliably differentiate a choroid plexus papilloma from a choroid plexus carcinoma on imaging are also highlighted through a systematic approach of a choroid plexus tumor.
