I don't know, the nurse that called just said it is there..Were you told what area of your brain it is in?
Meningiomas are tumors that originate from the meninges which are membrane-like structures that surround the brain and spinal cord.The dura, which is the outermost (and toughest) of the meninges covers the entire interior of the skull and invaginates into the brain creating "dural folds" and compartments within the interior of the skull such as the falx cerebri which separates the right side of the brain from the left side and the tentorium cerebelli which forms a "tent" that separates the cerebrum from the infratentorial space that contains the cerebellum and the brainstem within the posterior cranial fossa.
Typically, meningiomas are benign and slow-growing tumors, but instances of malignancy have been reported. Only about 10% of meningiomas occur in the spinal cord, while the majority occur intracranially. Intracranial meningiomas may occur in variable locations of the brain as dural-based, dome-shaped, round or oval, solitary masses. Rarely multiple concurrent meningiomas occur simultaneously in different locations of the brain. An unusual appearance for meningioma, called meningioma-en-plaque, has a flattened appearance that conforms to the curves of the brain and the inside of the skull.
Meningiomas represent the second most common type of tumor of the brain, accounting for approximately 20% of all primary intracranial tumors in adults. They are most common between the ages of 40 and 70 and they are more common in women than in men. Among middle-aged patients, there is a marked female predominance, with a female:male ratio of approximately 3:1. Meningiomas are extremely rare in children and only 1.5% of the total cases of meningiomas occur in the pediatric population.
