Abstract

Intracranial oligodendrogliomas show relatively low incidence among the itracranial tumors and difficult to differentiation with the other brain tumors. CT Plays an important role in the diagnosis of these lesions. Author sreviewed the 16 cases of pathologically proven oligodendrogliomas at Korea University medical center for recent 7 years and the results were as follows; 1. They showed biphasic age distribution, one peak in 2nd decade and another in 5th decade. 2. 14 cases (88%) located supratentorially and frequent in frontal lobe of the patient ageover 20(6/8), frequent in parietal lobe below 20(4/6). 3. Generally the tumors composed of solid portion but theyalmost always had some cystic or degenerative portion. 4. The diameter of the tumors varied from 2.5cm to 8cm. 5. The tumor calcification on CT scans were found in 14 cases and appearences were; 1) large irregular nodular calcifications; 5 cases 2) small nodular calcification; 4 cases 3) scattered stippled calcifications; 4 cases 4)shell like incomplete circular calcifications; 2 cases 6. 14 cases(88%) showed contrast enhancement, irregular enhancement in 5 cases, diffuse enhancement in 4 cases and ring like enhancement pattern in 5 cases.
