What is orbital meningioma?

Purpose of the Study: Orbital meningiomas are typically benign tumors, most commonly originating from the dura of the sphenoid wing or the optic nerve sheath. Procedures: We describe an unusual case of a malignant meningioma originating from the frontal lobe that ultimately produced orbital and distant metastases.

What is Spheno orbital meningiomas?

Objective: Spheno-orbital meningioma (SOM) is a rare intracranial tumor that arises at the sphenoid wing, extends into the orbit, and is associated with hyperostosis of the sphenoid bone. These tumors often invade important neurovascular structures around the orbital apex, superior orbital fissure, and cavernous sinus.

What causes hyperostosis in meningioma?

The floor of the middle fossa was a specific area of low sensitivity for preoperative assessment of associated hyperostosis. Conclusion: These results indicate that hyperostosis associated with meningiomas involving the cranial base are caused by tumor invasion of the bone histologically.

How do you get rid of an orbital tumor?

Orbital tumors may be treated with stereotactic radiosurgery. This is a non-invasive procedure where highly focused beams of radiation are directed at the tumor to destroy it. Chemotherapy, where cancer-fighting drugs are delivered into the bloodstream to seek out and destroy the cancer cells, can also be used.

How common are orbital tumors?

Conclusions: Orbital tumors in the senior adult population are malignant in 63% of cases. Malignant lymphoma is the most common tumor in this age group, accounting for 24% of cases. Overall, 25% of patients have systemic problems related to the orbital process develop, so systemic evaluation is warranted.

What is Hyperostosis meningioma?

Object. The hyperostosis frequently associated with sphenoid wing meningiomas is actual invasion of bone by the tumor. The intracranial portion of the tumor is usually thin with en plaque spread, and the tumor tends to invade the orbit through the superior orbital fissure.

How serious is a tumor behind the eye?

In addition to damaging vision, eye tumors can spread to the optic nerve, the brain and the rest of the body. Therefore, early diagnosis and treatment are extremely important. Melanoma tends to spread via blood vessels to distant organs.
