Suh, Lee, Kim, and Park: Diagnosis of meningiomas by computed tomography

Abstract

A review of CT findings in 30 cases, histologically proven cases of intracranial meningiomas is presented. Themajority of intracranial meningiomas revealed with classical CT features including, juxtadural locations, sharpmass delineation, high attenuation without contrast and homogenous contast enhancement. By these criterias, thediagnosis of meningiomas could be accomplished in 90% of cases. But some of meningiomas produce atypical featuressuch as irregular areas of nonenhancing mass, irregular ill-defined enhancing mass with large area of peritumoraledema, low density are within the mass represeting necorisi and cystic change. It is well known that CT is thebest and currently used modality in identifying the meningiomas. Polytomography as well as cerebral angiography,however, may often needed for detailed inforamtion about the nature and specific diagnosis of the meningiomas.
