Meningiomas are the most common non-glial tumor of the central nervous system (CNS).

Even though meningioma has a reasonably typical behavior, it is necessary to consider atypical forms; at the same time, some pathologies can mimic meningioma.

In this case, the CT aspect, while suggesting a meningioma, required an in-depth investigation to exclude the presence of metastases in the patient's clinical history, operated for breast cancer.

The MR appearance, as well as the presence of a dura tail, confirmed the diagnostic hypothesis of meningioma making the diagnosis essentially certain. 

Editorial note: a dural tail is not pathognomonic of a meningioma.
