Anaplastic ganglioglioma: case report and review of the literature.

A 10-year-old girl underwent radical decompression of a right temporal tumour extending to the insular cortex which proved to be a differentiated ganglioglioma. One year later, she presented with a bleeding right frontal tumour extending to the insula, the histology of which showed it to be the anaplastic variant of ganglioglioma. She underwent postoperative radiotherapy but died 6 months after the second operation. Anaplastic ganglioglioma is a rare variant of ganglioglioma and progression of the latter to anaplastic ganglioglioma is an extremely rare occurrence. The literature regarding ganglioglioma is reviewed.
