| ABSTRACT |
|
Approximately 1% of all the meningiomas arise from the extradural space. Intradiploic meningiomas constitutes only a very small percentage of this figure. Because of its rarity, it is often confused preoperatively with primary bone tumors of the skull. The intradiploic meningioma of the orbital wall may be considered as a subgroup of intradiploic ectopic meningioma. The following is our report of a recently observed case of intradiploic meningioma of the orbital wall without intracranial or intraorbital involvement. The preoperative tentative diagnosis was osteoma of the orbital wall. Nomenclature and histogenesis of this type of meningioma are discussed. |
