There is a great controversy concerning the management of the cystic wall. We reported six peritumoral cystic meningiomas and reviewed the literature to discuss the management of the cystic wall. Methods Six cases of peritumoral cystic meningiomas were retrospectively analyzed. Results Gadolinium-enhanced Tl-weighted magnetic resonance imaging scans disclosed the solid tumor enhancement in 3 cases, the cystic wall enhancement in 2 cases. One case only showed the cystic lesion. All the tumors were totally removed （ including the involved dura and partial cystic wall）. Histopathological examination showed 3 meningiotheliomatous meningiomas, 2 microcystic meningiomas, 1 mucoid degeneration. After operation, all the patients recovered well and demonstrated no neurological deficit. During the follow-up time, no tumor was recurrence. Conclusion Magnetic resonance imaging with contrast enhancement can provide information regarding whether surgical removal of the cystic wall is indicated. Peripheral enhancement of the cystic wall strongly indicates the presence of tumor infiltration. The removal of the entire cystic wall should be performed, excessive damage to brain be prevented.展开更多
