Abstract：
Xanthogranuloma (XG) of the sellar region is uncommon and is difficult to diagnose based on intraoperative frozen sections. This study is a case presentation and review of the literature, highlighting the need to explore underlying diseases in order to guarantee an accurate patient diagnosis. Herein, we presented the case of a 43-year-old woman who was afflicted with xanthogranuloma of the sellar region; the patient had a history of headache and lengthened menstrual cycles over the 6 months prior to presentation. Endocrinology tests revealed that the patient\'s levels of prolactin were high and the MRI of the patient showed a clearly defined sellar mass. As a result, the patient was considered to have prolactinoma prior to undergoing surgery. The tumor was completely removed using a transsphenoidal approach, and intraoperative frozen section revealed histology similar to xanthogranuloma. When the tumor was removed by surgical operation, the patient\'s visual field defects and headache were relieved. Although intraoperative frozen section should provide some guidance with regard to the diagnosis, a pathological study is conducted to confirm the actual diagnosis.
摘要：
鞍区黄色肉芽肿（XG）并不常见，很难根据术中冰冻切片进行诊断。本研究是一个案例介绍和文献综述，强调需要探索潜在的疾病，以保证准确的病人诊断。在这里，我们介绍了一例43岁女性,她患有鞍区黄色肉芽肿;患者在就诊前6个月有头痛史,月经周期延长.内分泌学检查显示，患者的催乳素水平高，患者的MRI显示明确定义的鞍区肿块。因此,患者在接受手术前被认为患有催乳素瘤.使用经蝶入路完全切除了肿瘤，术中冰冻切片显示组织学与黄色肉芽肿相似。当手术切除肿瘤时，患者的视野缺损和头痛得到缓解。虽然术中冰冻切片应提供一些关于诊断的指导，进行病理研究以确认实际诊断。
