Abstract
We report a case of fourth ventricular mixed germ cell tumor (GCT) in a 20-year-old man. Neuroradiological investigations revealed a fourth ventricular hemorrhagic tumor with adipose tissue. We suspected mixed GCT because adipose tissue was seen preoperatively, but mixed GCT occurring after childhood in this location has not previously been reported. We describe herein the imaging findings for mixed GCT and discuss the differential diagnoses of fourth ventricular tumors with adipose tissue.
