| 摘 要： | 目的探讨鞍区原发性脉络丛乳头状瘤的临床病理特征。方法对1例原发于鞍区的脉络丛乳头状瘤的影像学、组织病理学和免疫组化特征进行研究,结合文献讨论其临床病理特征及鉴别诊断。结果磁共振成像显示蝶鞍增大,其内可见团块状肿块,侵及鞍上池;脑室系统无异常。内镜经鼻蝶入路行肿物切除术。镜下观察可见肿瘤组织类似于正常脉络丛,呈乳头状结构,由单层或假复层柱状肿瘤上皮细胞围绕纤维血管轴形成。肿瘤细胞异型性小,细胞核圆或卵圆形,位于上皮基底部。免疫组化显示肿瘤细胞CK-pan、vimtentin、EMA和TTF-1(+),而S-100蛋白、神经胶质酸性蛋白、Syn和嗜铬粒蛋白(-)。结论原发于鞍区的脉络丛乳头状瘤非常罕见,影像学易与垂体腺瘤等相混淆。明确诊断依赖于病理组织学观察及免疫组化标记。外科手术完整切除可治愈。
