Chordoid glioma: report of a case with unusual histologic features, ultrastructural study and review of the literature.

Overview

Chordoid gliomas are an uncommon primary brain tumor with histologic features of a chordoma and immunolabeling for glial fibrillary acid protein. We report the 32nd case with a review of the literature. The clinical, radiographic and pathologic features of the tumor are presented with new pathologic findings adding support that this lesion may be of ependymal origin. Treatment and long term outcome are limited but chordoid gliomas appear to be indolent lesions that may be cured with gross total resection.
