Meningiomas in three different patients. (A) Sagittal CT and (B) sagittal postcontrast T1W MR images demonstrate a homogenously enhancing extra-axial mass lesion (red arrow) at the anterior cranial fossa/planum sphenoidale with small dural tails (blue arrows) and hyperostosis (white arrow). (C) Coronal CT and (D) coronal postcontrast fat-saturated T1W images show an anterior clinoid process meningioma (red arrow) with dural tails (blue arrows), hyperostosis (white arrow), and tumoral calcification. (E) Axial T2W and (F) axial postcontrast T1W images reveal a right cavernous sinus meningioma extending through the petroclival dura, tentorium, and paraclinoid dura. The mass completely encases the right ICA with significant narrowing (black arrows).
