Location based differential diagnosis
  • The “dural tail” sign can also be seen with other tumours such as
    • PXA
    • Schwannoma
    • Leptomeningeal metastasis
      • Meningiomas have usually a markedly elevated rCBV on PWI, which can be used to differentiate them from dural metastases, which tend to have a lower rCBV.
