The dural tail sign is a radiological sign that can be seen on MRI and, in some cases, on CT. It describes the attachment site, which appears on imaging as an extension of a mass lesion along the dura mater. The dural tail is typically found, for example, in meningiomas, but it may also be seen in other mass lesions, such as metastases1 2.
