| 中文摘要: |
| 鞍区占 位包括垂体起源的和非垂体起源的占 位性病变，其中以垂体腺瘤最为常见。 由于鞍区其他占 位性病变在颅内 的解剖
位置与 垂体腺瘤十分接近，因 此垂体腺瘤的诊断与 鞍区其它肿瘤的鉴别诊断， 是影像科医师所面临的挑战。 将鞍区其它少见的占
位性病变与 垂体腺瘤相鉴别， 给出正确的诊断对于指导临床手术入路和避免术中和术后出 现并发症（如脑脊液漏、颅内 感染）， 具
有重要意义。 其中鞍区占 位性病变常需要将垂体腺瘤与 Rathke 囊肿、颅咽管瘤、鞍区脑膜瘤、脊索瘤、颅内 转移瘤相鉴别 。 本文总
结了 目 前垂体腺瘤等其他占 位性病变的影像学表现以及影像学特征，以便于鞍区常见肿瘤的诊断和鉴别诊断。 |
| 英文摘要: |
| The sellar neoplasm includes pituitary and non-pituitary origin tumours arise in the sellar regions. The large majority
of sellar tumours are pituitary adenomas. Given their location, non-adenomatous lesions frequently mimic pituitary adenomas and can
pose a diagnostic challenge for the radiologist. Distinguishing rare sellar lesions from the common pituitary adenoma helps to direct the
correct surgical approach and reduce the risk of incomplete resection and/or complications such as cerebrospinal fluid leak with the
potential for meningitis. The purpose of this article is to review the imaging features of pituitary adenoma and other sellar tumours,
focusing on characteristics that may distinguish them from saddle common tumors . Lesions need to distinguish from pituitary adenomas
including Rathke cyst, craniopharyngioma, saddle area meningiomas ,chordoma and intracranial metastases. |
