SOLITARY OLIGODENDROGLIOMA OF THE OPTIC-N ERVE - A CASE-REPORT

Proptosis, decreased vision and oculo-motor palsies developed in the l eft eye of a 14-year-old girl, without neurofibromatosis signs. Comput ed tomographic (CT) Scans of the head and orbit showed a large fusifor m expansion of the left optic nerve without intracranial involvement. Magnetic resonance imaging improved contrast resolution over CT Scanni ng. A neurosurgical approach was performed and the optic nerve was res ected from the back of the globe to the intracranial portion. Microsco pic sections demonstrated oligodendroglioma, an unusual form of optic nerve glioma.
