RESUMEN
Many authors have been concerned with the diagnosis and management of meningioma which is widely-known to have a high incidence and that its total removal can result in a good prognosis. Magnetic resonance imaging (MRI) with gadolinium enhancement technique has enabled an easier diagnosis of meningioma. Among the radiographic signs of meningioma, the so-called meningeal "tail sign" is thought to be a highly specific sign for meningiomas. However, some cases of dural based tumors(lympoma, schwannoma, sarcoidosis) with the meningeal tail sign have recently been reported. Also, some authors have suggested that the meningeal tail sign may also been taken to indicate the extent of dural involvement of meningiomas. We report our experience of a case of metastatic brain tumor with the typical meningeal tail sign along with a review of the literatures. The findings of this case suggest that the meningeal tail sign is not a specific sign reserved only for meningioma.
