作者四年内切除鞍上与鞍内颅咽管瘤43例,其中有2例为垂体异位。例1,男,13岁,1977年出现视神经萎缩,CT扫描显示鞍内和鞍上有一囊肿。神经科检查:右眼失明,左眼鼻侧视野缺损。内分泌检查示发育迟缓和垂体功能减退。右前额入路开颅,发现在鞍内和鞍上有一囊肿,囊壁较厚,内含外胚层液化物。视神经向一侧移位,并有一灰红色圆形肿块悬挂于垂体柄上。该肿块被认为是异位垂体,经活检证实。
Within four years, the authors removed 43 cases of suprasellar and intracranial craniopharyngioma, of which 2 cases were pituitary ectopic. Example 1, male, 13 years old, optic nerve atrophy in 1977, CT scan showed a cyst in the saddle and suprasellar. Neurological examination: Blindness in the right eye, visual field defect in the left eye. Endocrine examination showed retarded growth and hypopituitarism. The right forehead craniotomy revealed a cyst in the saddle and the saddle, with a thick cyst wall containing ectodermal liquefaction. The optic nerve was shifted to one side and a gray-red circular mass was hung on the pituitary stalk. The mass was considered as an ectopic pituitary and confirmed by biopsy.
