Abstract
- Intracranial meningioma associated with cyst formation is unusual finding, which sometimes makes confusion in preoperative diagnosis. We experienced eleven cases of the cystic meningioma among 188 intracranial meningiomas who underwent operation from June 1989 to May 1993 at the Asan Medical Center. Clinical manifestations, findings of magnetic resonance imaging, preoperative diagnosis, and histopathology were analyzed. Among the 11 patients, the cyst of four were intratumoral type and seven were peritumoral type. There was no relationship between cyst formation and histological type of meningioma.
