Objective To discuss the characteristics of intrasellar meningioma on MRI.Materials and Methods The MRI appearances of 5 cases with intrasellar meningiomas verified by operation and pathology were analyzed retrospectively. Results 5 cases with meningioma were located in intrasellar region. 4 cases in the tuberculum sella, 1 case in the diaphragma sella. All cases were appeared as homogeneous evident enhancement. The pituitary glands in 3 of them were present, 2 of them were not present. The dura tails sign were appeared in 4, not in 1. The carotid artery were compressed and shifted in all of cases.Conclusion Homogeneous enhancement, visibility of the pituitary gland, the dural tail sign and compression of the carotid artery are the characteristics of the intrasellar meningioma.
