The clinical and pathologic characteristics of 25 patients with primary intraorbital meningiomas were reviewed. The racial and sex predilections and the histologic characteristics of the tumors were found to be similar to those of intracranial meningiomas, but the primary intraorbital meningiomas were found to be more common and more aggressive in children than are meningiomas in other locations. Meningiomas should be considered in the differential diagnosis of any lesion in a patient with progressive exophthalmos or visual loss, even in the first two decades of life, and the meningiomas should be treated surgically.
