Cystic meningiomas: report of two cases

Cyst formation with meningioma is extremely rare. Two cases of large peritumoral cystic lesions associated with intracranial meningiomas that simulated astrocytomas are presented. In each of these young patients, the cyst caused misdiagnosis pre- and intraoperatively. However, total excision was accomplished in each case. The pertinent literature is reviewed.
