Variante poco frecuente de meningiomas: meningiomas quísticos / Uncommon type of meningioma: cystic meningioma

Objective. To describe two (2) unusual cases of intracranial cystic meningioma whose diagnosis before surgery represents a great challenge. Description. Case Nº 1: male, 43 years old with generalized seizure. Ct scan shows a right frontal cystic tumor. Case Nº 2: female, 44 years old, with behavioral disorder and right brachiocrural palsy. Ct scan shows a left frontal cystic tumor. Intervention. In both cases surgery was performed with total resection of the tumor and the diagnosis was cystic meningioma. Very good results were obtained after surgery. Conclusion. Before surgery the diagnosis of cystic meningioma is seldom made. For this kind of cases, the treatment is, even now, a surgical procedure and in some cases radiotherapy.
