Intracranial Meningioma With Extra Cranial Extension Into The Frontal Sinuses
Meningioma is an all-around perceived tumor of the central nervous system, it rarely shows up as an extracranial tumor optionally outspreading into the paranasal sinuses. Meningiomas emerge from arachnoid cap cells that surround the brain, they are progressively developing and are generally not associated with significant cerebral edema. They manifest themselves by the pressure effects on circumscribing neural structures.1
Out of all intracranial meningiomas, almost 20% may have extracranial/extraspinal extension. Farr et al. reported orbital cavity as the commonest site of extracranial meningiomas .However, when the soft tissues, middle ear, orbit are precluded, the rate drops to under 1%. 2
