[Cystic meningioma: report of three cases].

Meningioma with cystic component is not a commonly encountered tumor. We report three patients with cystic meningioma histologically confirmed. Tomographic images of these tumours resembled those of a glial or metastatic origin with cystic or necrotic changes and were easily confused. In a 2-year period (1997-1999) in our Department we had three patients with cystic meningioma who account for 5.4% of all patients with meningiomas we have.
