垂体细胞瘤起源于垂体细胞，垂体细胞是源自室管膜谱系的改良神经胶质细胞，存在于垂体柄和后叶中。临床表现与其他垂体肿瘤相似，影像学检查可能提示垂体腺瘤。诊断基于组织病理学分析。可以采用经蝶入路手术治疗，效果良好。肿瘤全切除后预后良好。我们在此描述一名 17 岁患者的病例，该患者有持续性头痛和视力障碍病史。磁共振成像显示鞍区实性肿块增强，提示垂体腺瘤。经蝶入路切除鞍内肿块，经组织病理学分析后诊断为垂体细胞瘤。垂体细胞瘤是源自垂体细胞的罕见神经垂体肿瘤。它们的临床表现类似于无功能性垂体腺瘤，但这两种类型的肿瘤在组织学上截然不同。
Pituicytomas originate from pituicytes, modified glial cells derived from ependymal lineage that are found in the stalk and posterior lobe of pituitary gland. The clinical presentation is similar to other pituitary tumors and imaging exams may suggest pituitary adenoma. The diagnostic is based on histopathological analysis. Surgical treatment can be performed by transsphenoidal approach with good results. The prognostic is good after total tumor resection. We describe here the case of a 17-year-old patient with a history of persistent headache and visual disturbances. Magnetic resonance imaging demonstrated an enhancing solid sellar mass suggestive of pituitary adenoma. The intrasellar mass was resected through a transsphenoidal approach and the diagnosis of pituicytoma was made after histopathological analysis. Pituicytomas are rare tumors of the neurohypophysis derived from pituicytes. Their clinical presentation resembles that of non-functional pituitary adenomas, but these two types of tumors are histologically well distinct.
