Glioma

Glioma is a tumor of neuroectodermal origin. It is one of the most common primary brain tumors. Gliomas vary in degree of malignancy, histological features, the ability to progress, etc.

In the chiasmal-sellar region the most common are:

• glioma of the optic nerves, sometimes germinating into the orbit;
• 3rd ventricle bottom glioma;
• astrocytoma;

Non-specific signs of gliomas in the pituitary gland include:
