颅咽管瘤好发于鞍区，由于位于重要位置及复杂的毗邻组织结构，使开颅手术全切极为困难。肿瘤多呈囊性，目前国外学者多数主张采用立体定向技术内照射治疗，并已取得满意疗效[1，2]。我科于1989年3月-1998年9月应用CT立体定向胶体32磷内照射治疗颅咽管瘤16例，其中11例随访l－1 Craniopharyngiomas occur in the saddle area, due to the important location and complex adjacent tissue structure, making craniotomy completely cut extremely difficult. Tumors were mostly cystic, the current majority of foreign scholars advocate the use of stereotactic technique of internal radiation therapy, and has achieved satisfactory results [1,2].
