Highlights & Basics
- Benign nonglial epithelial central nervous system tumor, constituting 1% to 3% of intracranial tumors in adults, most often located near the optic chiasm.
- Bimodal age incidence with 50% in children aged between 5 and 14 years and a second peak in adults 50 to 70 years of age.
- Common acute presentations are sudden visual loss and symptoms of intracranial hypertension.
- Pituitary dysfunction is also common; children may present with growth failure and adults with diabetes insipidus and sexual dysfunction.
- Primary treatment consists of surgery. Following surgery, radiation therapy may be required.
