摘　　要：目的探讨MRI对本病的诊断价值。方法分析72例空泡蝶鞍综合征的临床表现及MRI表现,并对其病因,发病机理进行探讨。结果总结出空泡蝶鞍综合征的MRI征象有:(1)蝶鞍扩大;(2)鞍内被脑积液充填;(3)垂体受压变扁紧贴鞍底矢状位呈弧线样或新月形;(4)垂体柄延长,伸向鞍底;(5)可伴有脑积水等脑脊液压力增高征象;(6)可伴有脑肿瘤,脑囊虫等脑脊液压力增高病变。结论MRI对空泡蝶鞍综合征的诊断准确可靠,是影像学的最佳检查手段。Objective To explore the usefulness of MRI technique in the diagnosis of empty sella turcica syndrom (ESTS).Methods The clinical and MRI findings of 72 patients with ESTS were analyzed and discussed from its pathogenesis.Results On MR imaging ,ESTS in all patients were found to be the following features:(1)sella turcica;expanded(2)the inside of sella turcica was filled with CSF signal;(3)pituitary gland was pressed,flatted and neared the basis of sellaturcica so that showed as curvilinear or meniscus sign on sagittal scans;(4)pituitary handle prolonged and extended into the basis of sella turcica;(5)EST could company with hydrocephalus and increased sign of CSF pressure;(6)EST could company with tumor of brain and cysticercosis of brain as well as increased CSF pressure.Conclusion MR imaging is a best accurate and reliable method of current imaging techniques for diagnosing ESTS.
