| ABSTRACT |
|
The meningioma constitutes 12 to 16 percent of all intracranial tumors. Generally, meningiomas arise from intracranial arachnoid villi and located intracranially.
Extension of an intracranial meningioma onto the frontal and ethmoidal sinus occurs occassionally, but primary meningiomas of the frontal and ethmoidal sinus are extremely rare. The authors experienced a case of cystic, meningotheliomatous meningioma containing lamellated calcification involving of the lest frontal and ethmoidal sinus, which presented with protrusion of frontal bone and exophthalmos. In addition to our case, other types of extracranial meningioma are discussed with review of literature. |
