An 18-year-old man presented with progressive headaches, left face and tongue sensory change, and gait imbalance for four months. He had no significant past medical or family history. Magnetic resonance imaging (MRI) of the brain revealed a 4.7 x 4.4 x 3.9 cm right lateral ventricle mass, extending medially to compress the third ventricle and causing obstructive hydrocephalus. A gross total resection of the tumor was performed.
