The patient came for follow up of a pathologically proved left CPA meningioma managed with gamma knife radiosurgery. The mass lesion remained of the same size as compared to the previous study one year ago.

Schwannomas are more bright on T2 and often have cystic changes if reaches such size. The intracanalicular extension is a constant feature of CPA schwannomas as they arise from inside the canal, however, meningiomas can have intracanalicular extension if reaches large sizes as present in our case.

A dural tail is usually seen with meningiomas, however, it is non-specific and can happen with other extra-axial masses. It is usually smaller than what's seen in this case, so we suggest the added effect of radiation therapy for this dural thickening.
