Pure intrasellar meningioma is an extremely rare tumor that is difficult to diagnose as it resembles a pituitary adenoma in its clinical, endocrinologic, and radiologic presentation; it can only be distinguished through histopathologic examination. All previously reported cases of this lesion were considered those of pituitary adenoma at the initial diagnosis. This poses major challenges in clinical diagnosis. We report a case of a pure intrasellar meningioma in a 27-year-old man. A boundary between the tumor and pituitary gland may be evident on magnetic resonance imaging, thus enhancing the diagnosis of pure intrasellar meningioma.
单纯鞍内脑膜瘤是一种极为罕见的肿瘤，因其在临床、内分泌和影像学表现上类似于垂体腺瘤，故很难诊断；只有通过组织病理学检查才能鉴别。所有此前报道的此类病变均被初始诊断为垂体腺瘤。这给临床诊断带来了极大的挑战。我们报告了一例 27 岁男性的单纯鞍内脑膜瘤病例。肿瘤与垂体之间的边界在磁共振成像上可能是明显的，从而增强了对单纯鞍内脑膜瘤的诊断。
