Cystic or necrotic hypodense areas are occasionally seen within meningiomas on CT scan. The computerized tomography appearance of a cystic meningioma may simulate a glial or metastatic tumor with cystic or necrotic changes, and lead to an incorrect presumptive diagnosis. Radiological evaluation and recognition is important for the surgical removal of these potentially curable neoplasms. Such a case is presented and related literature reviewed.
