The pituitary fossa is an uncommon site for metastatic tumor spread. Metastatic lesions to the sellar area derived mostly from breast, lung, renal, prostate, and colon cancers, and rarely from other solid and hematologic malignancies. Almost every cancer has been reported as a source of pituitary metastasis. Pituitary metastasis can involve both the anterior and posterior lobes, but the neuro-hypophysis is mainly involved. Clinical manifestations include diabetes insipidus, hypopituitarism, headache, visual disturbances, ophthalmoplegia, and also compression of adjacent structures by aggressive tumor masses. Metastatic spread to the pituitary from a distant primary malignancy is commonly associated with metastases to other tissues and poor prognosis, unless efficient systemic targeted medical treatment is available for the primary cancer (melanoma, lymphoma).

转移性扩散到垂体。

垂体窝是转移性肿瘤扩散的罕见部位。鞍区的转移性病变主要来自乳腺癌、肺癌、肾癌、前列腺癌和结肠癌，很少来自其他实体和血液恶性肿瘤。几乎所有癌症都被报道为垂体转移的来源。垂体转移可累及前叶和后叶，但主要累及神经垂体。临床表现包括尿崩症、垂体功能减退症、头痛、视力障碍、眼肌麻痹，以及侵袭性肿瘤块压迫邻近结构。从远处原发性恶性肿瘤转移到垂体通常与转移到其他组织和预后不良有关，除非对原发性癌症（黑色素瘤、黑色素瘤、
