鞍上肿瘤可以原发于鞍上部位,如颅咽管瘤和脑膜瘤,也可以发自鞍内,如垂体腺瘤向上生长,穿破膈鞍延伸至鞍上部位。虽然肿瘤常可根据临床材料和颅骨X线平片检查得到诊断,但气脑造影检查仍属必要,特别在准备外科手术和放射治疗时,以便进一步确定肿瘤的大小、范围和邻近器官的关系。本文目的在于分析67例经手术及病理证实的鞍上肿瘤和鞍内肿瘤的气脑造影材料,以便观查被肿瘤所引起的造影变化和鉴别鞍上肿瘤与向鞍上延伸之鞍内肿瘤。肿瘤的病理类型与检查方法见表一。
The suprasellar tumor can be primary in the supraspinatus, such as craniopharyngioma and meningioma, can also be issued from the saddle, such as upward growth of pituitary adenomas, perforated diaphragmatic saddle extended to the upper part. Although tumors can often be diagnosed on the basis of clinical materials and skull radiographs, pneumo-angiography is still necessary, especially in the preparation of surgery and radiotherapy to further determine the size, extent and relationship of adjacent organs. The purpose of this paper is to analyze 67 surgically and pathologically confirmed suprasellar and intra-sellar pneumo-angiographic materials in order to investigate changes in contrast induced by tumors and to identify intra-suprasellar tumors extending to the suprasellar antrum. Tumor types and methods of examination in Table 1.
