The authors report a case of a white four-year-old boy with progressive neurological symptoms due to a brain stem mass lesion identified by computed tomography and magnetic resonance imaging scans. The diagnosis of gliosarcoma was confirmed by histological examination. This rare type of central nervous system tumor affects mainly patients over 40 years of age and is most commonly supratentorial. Only a few cases of gliosarcoma in children have been reported, particularly in the infratentorial region. The epidemiological data as well as the most frequent computed tomography and magnetic resonance imaging findings are discussed.
