Since Plater Felix called meningioma in 1614 for the first time, many authors reported about the diagnostic characteristics of meningioma in the way of incidence in radiology and pathology. In 1897, Obiei and Bollici described about the early radilogic patterns and Sossman and Putnam in 1925 analyzed detail radiologic findings for meningioma. Recently, early diagnostic criteria for meningioma by cerebral angiography is successfully done for better and confirmative preoperative diagnosis. Author collected 30 confirmed cerebral meningiomas and analyzed into plain skull X-ray and carotid angiography, mostly in Severance Hospital of Yonsei University. At the same time, author reviewed other reports in the literatures. Result: 1) Sexual incidence in author's report is much different from others that male patient are much more predominant in cerebral meningioma, in our hospital. 2) 23 out of 30 cases (88%) show in between 30 through 50 years of age. The oldest is 58 and the youngest 17 years of age. 3) Most of clinical symptoms are neurologic in origin (56%), and among them, headache (29%), convulsion and twitching (18%), and walking disturbance (15%) etc. are frequently complained, however, protruded eyeball (18%) can be visualized only in sphenoid or cribriform plate meningioma. Duration of illness are variable, and most of them show over 3 years which is suggestive of chronic benign brain tumor. 4) Prevalent site of meningioma in our 30 cases show; parasagittal (40%), sphenoid ridge (33%), cerebral hemisphere (17%) in location and they are most frequent 3 prevalent site of meningioma, reported as I others literature. 5) Radiologic Findings a) Simple skull series show 4 most important non specific findings of hyperostosis (82%), dorsum sellae erosion (96%), increased vessel grooves(57%) and localized bone destruction. However, psammoma calcifications are only 7% in incidence. Hyperostosis are frequently visualized in parasagittal meningioma, bone changes in s henoid ridge meningioma, and increased vessal grooves are frequent in parasagittal meningioma. b) 26 cases of cerebral angiogram are analyzed. Among them, non-specific findings are neovascularization (96%), displaced anterior cerebral artery (85%), circumferential vessels (81%), displaced middle cerebral artery (73%), Specific angiographic findings which is suggestive of meningioma are sharp deflection of vessels (92%), beading and irregular appearanced vessels (88%), simultaneous filling of external carotid artery (85%), displaced internal cerebral vein and venous angle (81%), and specific meningioma cloud is only 65%. Angiographic findings in 26 meningiomas are much different from Jacobson who described characteristic angiographic findings, which are sharp deflection of vessels, simultaneous filling of external carotid artery, and characteristic meningioma cloud mostly.
