ABSTRACT |
Meningioma is usually known to occur stuck to the dura mater, but extradural meningioma occurs rarely. Most of the extradural meningiomas are located in the head and neck and we report a case of the primary intraosseous meningioma in the orbit. A 50-year old woman presented with the left eye hyperemia and exophthalmos. Neuroimaging modalities showed hyperostosis at the left sphenoid and orbital wall. On microscopic view, spindle cells and psammoma bodies between the woven bones were observed. The origin of the intraosseous meningioma is explained with various potent possibilities and differential diagnosis thoroughly explored. |
