Meningioma arises from arachnoid cells imbedded in the dura and constitutes approximately 15% of all intracranial neoplasms. Its diagnosis could be made accurately on clinical grounds and characteristic appearances of plain X-rays and angiography, but computed tomography is undoubtedly the most accurate diagnostic method yet available. At the department of radiology, Kyung Hee University Hospital, 33 patients of intracranial meningiomas were examined with EMI 5005 CT scanner from October 1977 to July 1979. The following results were obtained. 1. The correct diagnosis was made in 31 out of 33 cases(94%). 2. The sex ratio was 20 females to 13 males and the greatest number of cases (36%) were seen in fifth decade. 3. The prevalent sites were convexity (27%). Flax(15%) and parasagittal (12%) in orders. 4. The precontrast scans appeared as isodensity in 16 cases (48%) , high density in 11 cases (33%) and hterogenous density in 6 cases(185). In contrast study, all of the meningiomas were enhanced and well defined. The most frequent enhancement pattern was dense homogrenous enhancement in 18 cases(55%). 5. Intratumoral calcifications of various extent were found in 7 out of 33 cases(21%). 6. Peritumoral low density area was present in 29 cases(885) and in tend to minimal in 66%, moderate in 31% and marked in 3%. 7. Tumor adjacent hyperostosis was found in 10 cases (30%). 8. All of meningiomas showed mass effects. 9. Two meningiomas were misdiagnosed as a pituitary adenoma and a glioblastroma multiforme.
