Results 5 cases with meningioma were located in intrasellar region. 4 cases in the tuberculum sella, 1 case in the diaphragma sella.

结果5例均位于鞍内,其中起源于鞍结节4例,鞍隔1例。5例均呈均匀明显强化。

Conclusion:Pituitary abscess should be considered when patients presented diabetes insipidus,hypopituitarism,sella bone erosion and sella neoplasm similar to a cyst tumor in CT or MRI.

若鞍区病变不大，但引起较严重的蝶鞍骨质破坏，表现为尿崩症和垂体功能低下时，应首先考虑垂体脓肿。

Conclusion The change of the relationship of the hapothalamus-pituitary-ovary and the hypotrophy of the pituitary may not cause the morphologic change of sella turcica.

绝经期妇女下丘脑—垂体—卵巢关系的改变及垂体腺肥大并不导致蝶鞍形态改变。
