Infratentorial oligodendroglioma in a child: a case report and review of the literature.

Oligodendrogliomas are the tumors of normal glial cells of brain called oligodendrocytes. They represent a small proportion of childhood brain tumors and are infrequently encountered in the posterior fossa. CT scan and MRI are very helpful for the preoperative management of oligodendrogliomas. However, due to the rarity and non-specific imaging features, it may be difficult to differentiate oligodendroglioma from astrocytoma especially in an infratentorial location. The short- and long-term outcome and the exact treatment protocol of posterior fossa oligodendroglioma is yet to be established. We report a rare case of an oligodendroglioma of the vermis in an 8-year-old female with a brief review of the literature.
