It is well known that the cell type ad histopathological grading of gliomas correlate well clinical course and prognosis. Therefore, it is tempting to set certain criteria that predict the histopathologic characteristics of the gliomas before the surgical intervention. With a total of 56 cases of gliomas which were verified histopathologically in Seoul National University Hospital between July 1978 and May 1983, a statistical analysis of the computed tomographic findings was done with the partcular emphasis on the correlation iwth histopathological features. The results are as follows : 1. The calcification is observed in 27 cases (48.2%) in total : in 20 cases (62.5%) among low grade group, in 6 cases (46.1%) among high grade group and in 1 case (9.1%) among glioblastoma multiforme group respectively. 2. The mass effect, especially surrounding low density correlates well with the grade of malignancy. 3. The contrast enhancement is observed in 43 cases (76.8%). The pattern of enhancement provides clues for the assessment of cell type and grade with fair degree of reliability. Among low grade group, 10 cases (31.3%) show no enhancement and 10 cases show solid enhancement. Among high grade group, 6 cases (46.8%) show solid enhancement and nodular or ring enhancement are not observed. Among glioblastoma multiforme group, 8 cases (72.7%) show characteristic thick irregular ring enhancement. 4. Plain CT densities are not useful in differentiating each group in statistically significant level. 5. Neither the margin of the mass nor th edegree of contrast enchancement contributes for the differentiation of each group. 6. Summarizing the above mentioned findings it is concluded that computed tomography is very helpful in differentiating the gliomas with regard to histopathological cell type and the grade of malignancy as well.
