Abstract
A prominent enhancement of the dura adjacent to meningiomas has been described as being pathognomonic of these tumors. We describe a case where a classic meningeal “tail sign” was associated with an extra-axial metastatic tumor attached to the tentorium. There was no tumor invasion of the dura. We conclude that this sign is nonspecific and can be seen with dural-based tumors other than meningiomas.
