摘要

1例垂体前叶缺陷患者,无尿崩症,CT和MRI扫描发现交叉后肿块伴大中窝囊肿,鞍内无组织(“空鞍”)。手术时,垂体柄缺失。交叉后肿块活检显示与垂体柄一致。最近对垂体后叶“异位”的MR可视化描述与垂体柄和后叶发育不全的病例有关。

Pituitary stalk agenesis: magnetic resonance imaging of 'ectopic posterior lobe' with surgical correlation.

A patient with anterior pituitary deficiencies, without diabetes insipidus, was found to have a retrochiasmatic mass in association with a large middle fossa cyst on CT and MRI scans, and no tissue in the sella ('empty sella'). At surgery, the pituitary stalk was absent. The retrochiasmatic mass was biopsied and shown to be consistent with pituitary stalk. Recent descriptions of MR visualization of an 'ectopic' posterior pituitary lobe are discussed in relation to this case of agenesis of the pituitary stalk and posterior lobe.
