A Case of Oligodendroglioma in the 4th Ventricle

At least 90% of oligodendroglioma have developed above the tentorium, especially in the frontal lobe, but the case of oligodendroglioma arising in the 4th ventricle of the posterior fossa is extremely rare, 0.08% of the total of intracranial tumors. It was first reported by Van Bogaert in 1928. We experienced a case of 11-year-old male patient admitted by headache, nausea and visual disturbance. The operation was performed after brain CT scan, vertebral angiography and ventriculography. But the patient died on the 66th hospital day due to generalized infection unfortunately. It was histopathologically diagnosed the primary oligodendroglioma of the 4th ventricle after autopsy.
