Abstract:
The purpose of this paper is to report a rare case of a pediatric pineal gliosarcoma. Gliomas on the pineal region are uncommon, representing 0.4%-1% of all brain tumors. Furthermore, pediatric gliosarcomas are a very rare entity. We present a case of a 5-year-old girl, with a history of headache, vomiting, diplopia, and gait disturbances. A pineal tumor was found with pathology results consistent with a gliosarcoma. A total of 25 cases of pediatric gliosarcomas have been reported, none of them in pineal topography. Only 3 gliosarcomas were found in the pineal region, but these were found in adults. To our knowledge, this is the first pediatric pineal gliosarcoma reported in the literature.
