  diaphragma sellae
Microscopic analysis of the vascular bed in the diaphragma sellae reveals that there are fine arterial filaments mostly in the superior layer, while venules are situated in the inferior part of the diaphragm.
      
The diaphragma sellae in every case bulged upward with a convex domed appearance.
      
Identification of the diaphragma sellae, possible only on the unenhanced short TR/TE sequence, was crucial for differentiating the lesion from a pituitary adenoma, and therefore for the correct surgical approach.
      
Pituitary macroadenoma and diaphragma sellae meningioma: differential diagnosis on MRI
      
Diaphragma sellae meningiomas are unusual tumours often not distinguished from pituitary macroadenomas.

Angiotomography is also useful for the differential diagnosis of empty sellae.
      
Signs attributable to increased intracranial pressure, mainly erosion of the dorsum sellae, were found in about half of the cases.
      
Microscopic analysis of the vascular bed in the diaphragma sellae reveals that there are fine arterial filaments mostly in the superior layer, while venules are situated in the inferior part of the diaphragm.
      
The lesions demonstrated included empty sellae and suprasellar extensions of pituitary tumours.

The intercavernous sinuses of 30 adult specimens were examined under the operating microscope. Both the anterior intercavernous sinus(AIcS) and the inferior intercavernous sinus(ⅡcS)are present in 93.3% cases.The AIcS appears as a triangle canal in majority but the most ⅡcS as a split dural space.The AIcS relates closely to the peripheric border of the adenohypophysis and the ⅡcS contacts with the inferior surface of the adenohypophysis.The posterior intercavernous sinus(PIcS) is present in 53.3% cases and relates...

在手术显微镜下解剖观察了30例成人头颅标本的海绵间窦。前间窦出现率93.3%,多呈三角形,主要位于鞍隔前缘与鞍前壁的硬脑膜转折处,与腺垂体周缘紧密相邻。下间窦出现率93.3%,多呈裂隙状,主要位于鞍底硬脑膜内,与腺垂体下面相贴。上述两窦特别宽大者各2例,为经蝶窦入路垂体切除术的禁忌症之一。后间窦最小,出现率53.3%,位于鞍隔后缘与鞍背的硬脑膜转折处,下邻垂体后叶上端。与垂体中间部相对处,垂体硬膜囊内层内凸成嵴,嵴内有垂体下动脉穿行。此嵴可作为垂体前、后叶的分界标志。

This study analyzed forty cases of empty sella turcica diagnosed by MRI, including the appearance and discussed the mechanism.

本文对MR诊断的40例空泡蝶鞍临床表现及影像改变进行分析,结合文献对其发病机理、临床特点进行探讨,提出本征与先天鞍隔缺损、脑脊液压力增高、垂体肥大继之萎缩有关,多为女性,中年肥胖者。MR特征为:垂体压扁至鞍底,冠状位呈“锚”形,鞍内充满脑脊液。

Seven cases of empty sella syndrome were reported,among them 2 cases were primary empty sella syndrome,5 cases were secondary empty sella syndrome. 5 cases were operated with the ob-literation by transsphenoidal approach,2 cases were operated by transfromal approach.6 cases were cured,the symptoms in one case was not improved due to the primary hydrocephalus.This syndrome is associated with defect of sellar diaphragm,benign intracranial hypertension,long-term administration of Bromocriptine,surgery and radiotherapy...

Seven cases of empty sella syndrome were reported,among them 2 cases were primary empty sella syndrome,5 cases were secondary empty sella syndrome. 5 cases were operated with the ob-literation by transsphenoidal approach,2 cases were operated by transfromal approach.6 cases were cured,the symptoms in one case was not improved due to the primary hydrocephalus.This syndrome is associated with defect of sellar diaphragm,benign intracranial hypertension,long-term administration of Bromocriptine,surgery and radiotherapy of pituitary gland.Main clinical features are headache,damage of vision and visual fields,hypopituitarism. Obliteration of empty sellar by transsphenoidal ap-proach is a simple and effective method.

报道7例空蝶鞍综合症,其中原发性2例,继发性5例。经蝶窦进路法充填法手术治疗5例、经额进路治疗2例。除1例因有原发性脑积水未愈外,余6例治愈。本病与鞍隔缺损、良性颅内高压、长期服用嗅隐亭、垂体手术或放疗后有关。临床以头痛、视力视野损害和垂体功能低下为主要特点。经蝶窦充填法治疗是简单有效的方法。
