Meningiomas can grow in almost any part of the skull, and larger meningiomas usually produce neurological compression and require surgical removal. However, the different sites of meningioma growth make significant differences in the relationship between meningioma and surrounding tissue structures. The surgeon’s pre-surgical examination and preparation to clarify the origin, size, blood supply, and relationship to neurovascularity of meningioma as much as possible will help to completely remove the tumor and protect the function of the brain tissue surrounding the tumor. For general meningioma, the diagnosis of meningioma, the size of the tumor and the extent of meningeal invasion can be clearly determined by MRI, and the origin of the meningioma can be determined so that the blood supply to the base of the tumor can be isolated and the tumor can be removed during surgery. For meningiomas at the base of the skull or invading bone, a CT of the head is required to observe the extent of meningioma erosion or damage to the skull. For meningiomas that invade veins or venous sinuses, MRI or CT imaging of the veins is required to clarify the extent of tumor invasion of the veins and to determine the treatment of the venous sinuses during surgery. For meningiomas around large blood vessels in the brain, MRI or CT imaging of the arterial vasculature is usually required to clarify the relationship between the arterial alignment and the meningioma. In addition to the routine physical assessment of the meningioma, the necessary MRI sequences or CT examinations of the head are required to give the surgeon more information about the tumor prior to surgery. The relationship between the tumor itself and the surrounding meningioma, bone, blood vessels, nerves and other important structures can help reduce the risk of surgery and increase the chances of complete meningioma removal.
