This study is to investigate the clinical significance of diaphragma sellae in patients with pituitary adenoma by MR images. A total of 47 cases of pituitary adenoma patients were enrolled in this study. Preoperative and postoperative MR scanning together with preoperative 3D-GE sequential scanning were performed. A series of parameters of diaphragma sellae were measured and compared. Tumor hei...

background and importance: symptomatic vasospasm is a well-known pathology associated with ruptured aneurysms. nevertheless, this condition is rarely found as a result of skull base tumor removal. case presentation: we reported a new case of 40-year-old woman previously treated for a tuberculum and diaphragma sellae meningioma showing symptomatic vasospasm after twelve post-operative days witho...

The diaphragma sellae (DS) is a fold of dura that forms a partial roof over the pituitary gland. The foramen of the diaphragma sellae (FDS) is thereby a pathway for suprasellar extension of pituitary tumors. The purpose of this study was to describe the anatomical dimensions of the DS and FDS and to understand the relationship of FDS with the overlying optic chiasma. The study was conducted in ...

Sella turcica is a saddle shaped depression in the sphenoid bone. It received its name from its resemblance to the Turkish saddle. The seat of the saddle is known as pituitary fossa or hypophyseal fossa. The pituitary gland or hypophysis cerebri is situated in the hypophyseal fossa. It is limited anteriorly, posteriorly and inferiorly by bony constituents of the sella turcica the tuberculum sel...

In reading the well documented article by Davis et al. [1] in the November/December 1984 issue of AJNR, we found the title of the article to be perhaps a bit provoking and the authors' conclusion rather severe for high-resolution computed tomography (CT) of pituitary microadenomas. Two points should be emphasized: 1. The authors are correct in stating that "gland height greater than 8 mm and an...

The appearance of the diaphragma sellae is described in cryomicrotomic sections and on MR in patients with and without intraand suprasellar masses. On MR, it appears as a thin band of negligible signal that is best shown when adjacent CSF or a mass has greater signal intensity. Its position or absence can be used to differentiate intrasellar masses with suprasellar components from suprasellar m...

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 alon...
