Meningiomas

Abstract

Meningiomas are the most common primary central nervous system tumors and account for about one third of all primary brain and spinal tumors. They are classified according to the World Health Organization into 3 groups (I–III). Treatment strategies range from observation, surgery, and/or a radiation therapy. Many meningiomas are slow growing and discovered incidentally. Symptoms can vary widely, depending on the location. Patient’s specific factors and the location of the meningioma in relation to critical brain structures are all important factors in determining the optimal treatment. This chapter presents common clinical scenarios of meningioma. Differential diagnosis, perioperative workup, surgical nuances, and postoperative complications are discussed.
