垂体瘤是较为常见的颅内肿瘤,其发病率仅次于胶质瘤和脑膜瘤,各种文献统计约占颅内肿瘤的10%~([1,2])。鞍区肿瘤中,垂体瘤的发病率为首位。在人群中的发病率以青春期和生育期女性为多见,常有内分泌功能紊乱征象,巨大的垂体瘤可压迫周围重要结构如颈内动脉、视交叉、下丘脑导致相应的临床体征。磁共振动态增强技术能够动态、客观、准确地反映垂体微腺瘤的血供特征,使得对垂体微腺瘤诊断的敏感性及准确性得到极大的提高。
Pituitary tumor is a more common intracranial tumor, its incidence is second only to glioma and meningioma, various literatures account for about 10% of intracranial tumors ~ ([1,2]). Saddle area tumors, the incidence of pituitary tumors first place. The prevalence in the population of adolescent and reproductive women are more common, often endocrine disorders signs, a huge pituitary tumor can compress the surrounding important structures such as the internal carotid artery, optic chiasm, hypothalamus lead to the corresponding clinical signs. Magnetic resonance dynamic enhancement technology can dynamically, objectively and accurately reflect the blood supply characteristics of pituitary adenoma, making the diagnosis of pituitary adenoma sensitivity and accuracy has been greatly improved.
