Review of 22 cases of meningioma indicates that this lesion occurs slightly more frequently on the left but without predilection for sex or age of the patient. The presenting symptoms were nonspecific. Plain radiographs of the skull sometimes demonstrated calcification in the tumor, but more often did not. Cerebral angiography frequently showed enlargement and displacement of the anterior choroidal artery on the side of the tumor; the lateral posterior choroidal artery on the side of the tumor was also enlarged and displaced in seven of nine patients who underwent vertebral arteriography. Pneumoencephalography accurately demonstrated the site and size of the lesion, as did radionuclide scanning if the lesion was vascular. Computerized tomographic (TC) scanning also determined the location and size of the tumors, as well as their mass effect and vascularity; CT scanning also demonstrated calcification that was not visible on the plain skull radiographs in two of six patients who underwent CT scanning and had calcification.
