Meningiomas arising from the optic nerve or secondarily invading the orbit from the intracranial cavity are uncommonly encountered in children. Ectopic (extradural) meningiomas are exceedingly rare orbital tumors that do not originate from either the optic nerve or the intracranial meninges. We evaluated and treated two boys aged 7 and 10 years with probable primary ectopic (extradural) orbital meningiomas. Both patients presented with a gradual onset of progressive, painless proptosis. In addition, computed tomographic scans demonstrated involvement of the superomedial orbit without bony erosion or hyperostosis, but with expansion of the adjacent sinus. Neither tumor demonstrated attachment to the optic nerve or intracranial extension at the time of surgery. Both patients were successfully treated with complete surgical excision. Evaluation did not reveal the presence of neurofibromatosis in either child.
