Abstract

Most intrasellar meningiomas are located in the subdiaphragmatic and supraglandular region because they originate from the diaphragma sellae. Subglandular meningiomas located under the pituitary gland are extremely rare. Intrasellar meningiomas in the subdiaphragmatic and subglandular region probably originate from the dura in the sellar floor. We report a case of a subglandular meningioma along with a review of the literature.

  Fig. 1 Subglandular meningioma from floor of sellar turcica. Sagittal T2- (A) and T1- (B) weighted MR images show intrasellar mass measuring approximately 1.8 × 1.7 cm, with slight suprasellar bulge. Mass shows homogenous isointense signals except for focal inhomogenous signal on T2-weighted image. Contrast enhanced sagittal (C) and coronal (D) T1-weighted MR images shows intrasellar mass with two compartments of different enhancement; upper lesser-enhancing compartment (arrow) is confirmed to be normal pituitary gland and lower greater-enhancing compartment (arrowhead), as meningioma. E. Photomicrograph (Hematoxylin & Eosin staining, × 100) shows mixture of acidophils and basophils in upper region (up-down arrow), corresponding to normal pituitary gland tissue. lower region is confirmed to be meningioma (arrow), containing whirls of cells (arrowhead).
