By Rutten, Isabelle; Cabay, Jean-Evrard; Withofs, Nadia; Lemaire, Christian; Et al Precise delineation of the shape of skull base meningiomas is critical for their treatment and follow-up but is often difficult using conventional imaging such as CT and MRI.

Between 1997 and 2002, 456 patients with an intracranial meningioma were treated. Thirty-nine of these had more than one meningioma (8.6%). The mean age was 58 years (27-85 years). Sex distribution was 8.8: 7 (35 female, four male). There was no associated spinal meningioma.

A patient who had been treated for bilateral breast carcinoma subsequently developed a metastatic breast lesion in a meningioma. Although it is not uncommon for more than one tumor to occur in the same patient, metastases from one tumor into another tumor are rare ("tumor to tumor" phenomenon).
