## Abstract

Choroid plexus tumors (CPTs) are rare neoplasms. Patient presentation varies depending on the location of the lesions. Gross total resection of primary lesions remains the gold standard for surgical treatment of CPTs. Here, we present the case of a 22-year-old male patient with 2-day history of abnormal body movement and headache who was found to have an enhancing mass of the lateral ventricle. The patient underwent craniotomy for gross-total resection of the lesion, with final histopathology demonstrating WHO Grade II aCPP.
