Endosellar meningiomas: report of 2 cases and review of the literature

Two cases of endosellar meningiomas are presented. The clinical and radiological picture is not always sufficiently specific to distinguish meningiomas from other types of sellar lesions, but pre-operative diagnosis is of fundamental importance in choosing the best surgical approach. In both cases, the transsphenoidal approach was used, and due to the dense consistency of the tumors, only biopsies were performed. One of the two patients was reoperated on using the sub-frontal approach for radical removal of the tumor. In the authors' experience, craniotomy proved to be the more favorable approach than the transsphenoidal route for radical excision of endosellar meningiomas. Literature on the classification of sellar meningiomas for radiological diagnosis and surgical strategy of endosellar meningiomas is reviewed.
