ABSTRACT
Cystic Meningiomas are rare tumor. There is a clear prevalance in infants, according for 10~19% of all intracranial meningiomas in this age group, compared with only 2~4% in adults. But, reports of cystic meningioma have been increased in frequency since the introduction of computed tomography(CT) and magnetic resonance image(MRI). Authors report two cases of cystic meningioma in adults. Radiological finding showed extraaxial mass with cystic component. Authors performed total surgical resection of the tumor mass and of the entire cystic component with cystic wall in both patients. Postoperative histopathological diagnosis of the tumor mass was a transitional meningioma in both patients. Both patients showed favorable prognosis and no recurrence findings in follow up MRI.
