Meningiomas comprise approximately 20% of adult intracranial tumors, have a female predominance, and occur most often during middle and older ages... They may be found in intracranial and intraspinal compartments... The majority of meningiomas are histologically benign tumors, arising from the cap cells of the arachnoid layer... While the overwhelming majority of meningiomas are histologically benign, the malignant type may result in rapid, widespread infiltration with small (microscopic) "finger" projections into adjacent cortex... Noncontrast CT's of meningiomas often reveal sharply demarcated, rounded, homogenous masses with slightly increased density when compared to surrounding cortex... Treatment Options A variety of clinical and experimental treatment options exist, including surgery, radiotherapy, stereotactic radiosurgery, brachytherapy, chemotherapy, and hormonal therapy... Resection is the most widely utilized treatment option, although advanced age, concern about loss of neurological function due to surgery, advanced age, and being a poor surgical candidate preclude some from surgical options... Likewise radiotherapy after incomplete resection of a meningioma may be of considerable benefit to patients... Since this technology is relatively new, long term outcome of gamma knife therapy is not known... Brachytherapy with iodine-125 has been described in the literature; long term outcomes have yet to be determined... Medical treatment options include recommendations of anticonvulsant prophylaxis in patients with supratentorial masses; corticosteroids to reduce brain swelling may also be warranted.
