Orbital Meningiomas are slow growing neoplasms. They can affect the cavernous sinus, optic nerve, and the intraorbital contents. Orbital meningiomas may also invade adjacent orbital tissue, bone, dura and muscle. These meningiomas are more common in adults and are rarely seen with children. Symptoms may include proptosis, visual disturbances, diplopia, and headaches. CT may be utilized for diagnosis, but a MRI is the modality of choice. Thinner slices of the orbits are utilized along with contrast to demonstrate the hyperintense tumor. The treatment plan depends on the age of the patient. With older patients follow up MRI's are utilized. With older patients these meningiomas tend to grow at a much slower rate. Younger patients usually under the age of 40 seem to have more aggresive lesions and should be removed surgically. A side effect from surgery may be visual loss due to the origin of the meningioma and size. After surgical removing, patients' prognosis is great with recurrences being very rare.
