title: Orbital Recurrence of Ethmoid Sinus Malignant Meningioma: Case Study and Literature Review.
abstract: The authors describe a case of a recurrent World Health Organization grade III extradural, sinonasal meningioma that presented with epiphoria. Primary extradural meningiomas are rare, comprising only 1% to 2% of all meningiomas. These tumors are diagnosed and graded histologically according to the World Health Organization criteria. Grade III tumors are very malignant with high recurrence and death rates. This case highlights the rarity of sinonasal tract meningiomas involving the orbit. In addition, it shows the poor prognosis of such malignant disease and the need for a multidisciplinary approach. Collection and evaluation of protected patient health information for this report was in compliance with the Health Insurance Portability and Accountability Act and approved by the Institutional Review Board of Northwestern University Feinberg School of Medicine. Research adhered to the tenets of the Declaration of Helsinki.
