ABSTRACT |
Since its earliest description in the 18th century, meningioma has been considered a relatively indolent benign tumor which can be completely removed. Some grow very quickly, however, recur more frequently and with each recurrence, may change their biology to a more malignant form. A meningioma rarely metastasizes to the extracranium; the most frequent extracranial metastatic sites include the lung, musculoskeletal system and lymph node. The authors report a rare case of meningotheliomatous meningioma which occurred in the left parasagittal area and invaded the superior sagittal sinus; after surgery, it showed multiple recurrences and regrowth, and finally metastasized to the left thoracic cage. The authors also reviw the literature. |
