Chordoid glioma  is a recently recognized tumor that has a typical

 location in the anterior third ventricle and hypothalamic region, 

with histologic features distinct from those of other glial tumors

mucinous background, with low-grade lymphoplasmacytic 

infiltrate, similar to chordoma or chordoid meningioma.
