Abstract
- The intracranial meningioma represent 155 of all intracranial tumors in adult and CT is the most useful foridentifying 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 ofperitumoral edema. The authors reviewed 88 cases of meningioma confirmed pathologically in Koea University MedicalCenter for recent 4 years. Among them, 14 cases had unusual CT findings. We described and analized atypical CTfindings 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 desntiy mass with thick rime enhancement in 2cases. There is one case of multiple lesions.
