Abstract
A seven-year old female with primary megalencephaly and pseudopapilledema has been followed for over four consecutive years. Physical examinations of the patient and her family, funduscopic photography, and fluorescein angiography have failed to identify the etiology of her pseudopapilledema. Macrocephaly and pseudopapilledema have been seen in association in only one previous report to our knowledge. The importance of distinguishing pseudopapilledema from true papilledema in children with large heads is reviewed.
