Intraorbital ganglioglioma of optic nerve in a patient with neurofibromatosis type 1.

We report the case of an orbital optic nerve gangliogoma in a 55-year-old woman with neurofibromatosis type 1 (NF1). Clinical course neuroimaging findings, pathology, and treatment options of gangliogloma are discussed and contrasted with pilocytic astrocytomas of the optic nerve, a much more frequent visual pathway neoplasm in NF1 patients.
