Abstract
Brat et al. (J Neuropathol Exp Neurol 57 : 288–¶290, 1998) reported eight cases of a new clinico-pathological entity, which occurs mainly in the third ventricle of middle-aged females, which they described as chordoid glioma of the third ventricle. We report a new case of a 41-year-old woman with a suprasellar chordoid glioma with histological, immunohistochemical and ultrastructural studies. We discuss the differential diagnosis between chordoma, chordoid meningioma, germinoma and pituitary adenoma. Histologically, the tumour showed cords and lobules of isomorphic epithelioid cells in a vacuolated matrix with prominent multifocal lymphoplasmacytic infiltrates in which some histiocytes and isolated Touton-type giant cells were seen; cells were immunoreactive for glial fibrillary acidic protein but negative for epithelial membrane antigen. Ultrastructural examination revealed abundant intermediate filament but no desmosomes, microvilli nor cilia were seen.
