Radiology of meningiomas.

Modern imaging plays an important role in the management of the patient with a meningioma. From initial diagnosis to postoperative evaluation and follow-up studies, the radiologist must be aware of the various and sometimes atypical imaging appearances of meningioma. This is often very satisfying since the imaging characteristics of meningioma are usually, but not always, diagnostic. This manuscript will briefly review the historical development of the imaging of meningioma and then describe the typical and atypical imaging appearances of this very common intracranial tumor.
