Background : A 48 year-old woman with nasal mass and an 8-year history of bilateral hearing loss, developed loss of vision
on her right eye for 1 year. Her eye examination showed best corrected visual acuity of 6/12, 6/7.5, and exophthalmos with a
deficit in adduction and abduction, a relative afferent pupillary defect and swollen optic disc on her right eye. Her brained CT
showed characteristics of craniofacial fibrous dysplasia which were expansile with bilateral sclerotic ground glass and cystic
lesion, predominantly at sphenoid and temporal bones. The mass extended to infratemporal fossa, surrounding pterygoid
bone at right nasopharynx and at frontal region.
Objective : To report a case with meningioma mimicking craniofacial fibrous dysplasia.
Material and Method: A right craniotomy for tumor resection was performed.
Results : Histopathology revealed a meningioma.
Conclusion : This is a rare case of meningioma with an initial manifestation as well as a brained CT finding showing features
of craniofacial fibrous dysplasia.
