Meningioma
Meningiomas are benign tumors which arise from the arachnoid cells that form the arachnoid villi, which are seen in association with the dural sinuses. Meningiomas comprise between 13 to 18% of all intracranial tumors. Meningiomas are the second most common tumor of the cerebellopontine angle. Meningiomas tend to occur more frequently in females than males. They are most common in the fifth decade of life but can be seen over a wide age range. The presence of a meningioma outside the central nervous system is considered to be ectopic. These ectopic meningiomas are differentiated by their connection to the central nervous system (primary) or without a central nervous system connection (secondary). The most common location for ectopic meningiomas to occur in the head and neck region is the middle ear and the temporal bone. Symptoms may include hearing loss, dysequilibrium, headaches, and cranial nerve abnormalities. The treatment of choice is complete surgical excision. Malignant change rarely occurs.
