title: Extracranial sinonasal tract meningioma: a case report.
abstract: Extracranial meningioma is an unusual tumor, mainly found in the head and neck area. Before surgical removal and histopathological examination, this diagnosis is rarely considered. We report a case of an extracranial meningioma located in the frontal sinuses of a 65-year-old-woman. Symptomatology included trouble of vision due to bilateral exophtalmos and mild headaches. Bilateral exophtalmos was secondary to the development of huge frontal mucoceles. These mucoceles grew slowly due to the frontal recesses blockage by the extracranial meningioma. External approach was performed with removal of the mucocele walls and of the extracranial meningioma itself. The frontal recesses were blocked with synthetic cement, and orbital roofs were reconstructed with a polydioxanon-sheet (PDS). Frontal sinuses were excluded and filled with bone bank grafts. A review of the literature on extracranial meningioma and a discussion about the surgical management of this case are proposed in this paper.
