Intracranial cystic meningioma.

Two cases of intracranial cystic meningiomas are reported. Neuroradiological and intraoperative diagnoses in both cases were cystic astrocytoma. However routine biopsy during the intra-operative period and an accurate interpretation during frozen-section will establish the diagnosis of cystic meningioma. Complete excision of cyst wall of the meningioma during the surgery will minimise the incidence of recurrence of these benign tumours.
