Three cases of an entirely suprasellar symptomatic Rathke's cleft cyst, two of which were associated with normal sella turcicas, are reported. In all cases, the cysts caused compression of the optic chiasm, and two produced hypothalamic dysfunction. The diagnosis of these entirely suprasellar masses was enhanced by metrizamide cisternography. Two cases were treated by frontal craniotomy and one was treated transsphenoidally, with good results in all cases. The radiology, pathology, and surgical treatment of these unusual cases is presented. An embryological pathogenesis for the occurrence of an entirely suprasellar Rathke's cleft cyst is discussed.
报告了3例完全位于鞍上的有症状的拉克氏裂囊肿，其中2例蝶鞍正常。所有病例中，囊肿均导致视交叉受压，2例出现下丘脑功能障碍。甲泛葡胺脑池造影有助于诊断这些完全位于鞍上的肿块。2例采用额部开颅手术治疗，1例采用经蝶窦手术治疗，所有病例效果良好。本文介绍了这些罕见病例的放射学、病理学及外科治疗情况。并讨论了完全位于鞍上的拉克氏裂囊肿发生的胚胎学发病机制。
