Abstract
- We experienced the unusual C.T. finding of meningioma recently. Classical C.T. finding of meningioma reveals found homogenous high density or isodensity in the plain C.T. and homogenous marked enhancement in the postinfusion C.T. But, some of meningioma demonstrates atypical features such as irregular areas of nonenhancing mass, irregular ill-defined enhancing mass with large area of peritumoral edema, low density area within the mass representing necrosis and cystic change. C.T. finding that we experienced revealed ring-formed high density in the plain C.T. and homogenous strong enhancement in the postinfusion C.T.
