• In 33 histologically verified intracranial meningiomas, the correlation between the pattern of the time-signal intensity curve (TIC) from dynamic MR imaging and the histological subtypes were studied. The patterns of TIC for meningiomas were classified into two types: type A with a steep rise to a peak within a short time; type B with a slow rise to a peak followed by a plateau. Of the 16 meningiomas of the meningothelial type, 14 (87%) were type A on the TIC. On the contrary, all of the fibroblastic meningiomas were type B. The others had an almost equal distribution between the two types. These results indicate that dynamic MRI does not always have a predictive value for the histological subtype of an intracranial meningioma or for the histological architecture of the meningothelial or fibroblastic components.
