How are meningiomas diagnosed?

Diagnosing meningiomas can be difficult due to the slow rate at which they grow. Often, the symptoms are attributed to aging. Thorough neurological exams are needed, the diagnosis is most often made with radiological tests. Other tests such as hearing and vision tests may be used to determine how a meningioma is affecting the brain.

What tests are used in diagnosing meningiomas?

Computed tomography (CT scans) and magnetic resonance imaging (MRI) are often used in the diagnosis. A full diagnosis may require a biopsy, however, sometimes the diagnosis can be made by CT or MRI alone. On rare occasions, a cerebral angiogram may be used to determine the source of blood to the tumor, or how the tumor is affecting blood flow in the brain.
