Intraventricular and pineal region tumors represent 2% of all primary central nervous system tumors but have many unique features. Because many patients present with symptomatic hydrocephalus, urgent treatment of the tumor or hydrocephalus is often needed. Both benign and malignant tumors can arise in these regions, and often radiographic imaging is non-diagnostic.
