The intracranial meningioma represent 15% of all intracranial tumors in adult and CT is the most useful for identifying the meningiomas. Most intracranial meningiomas have typical CT findings of round sharply delineated isodence or hyperdense tumor in a juxtadural location with intense homogenous enhancement and mild degree of peritumoral edema. The authors reviewed 88 cases of meningioma confimed pathologically in Korea university Medical Center for recent 4 years. Among them, 14 cases had unusual CT findings. We described and analized atypical CT findings of these 14 patients. Atypical findings consisted of irregular eccentric low density in 4 cases peripheral cyst formation in 3 cases marked edema in 3 cases low density mass with thick rim enhancement in 2 cases.
