垂体瘤是发生在垂体上的肿瘤,通常又称为垂体腺瘤,是常见的神经内分泌肿瘤之一,约占中枢神经系统肿瘤的10～15%。绝大多数的垂体腺瘤都是良性肿瘤。随着MRI扫描技术在临床上的广泛使用,使垂体瘤的诊断敏感性和特异性明显增加[1]。我科就手术和病理证实、MRI平扫+增强的42例垂体瘤进行回顾性分析探讨,以总结MRI增强扫描在垂体瘤诊断中的意义。垂体腺瘤来源于垂体前叶上皮细胞的良性肿
Pituitary tumor is a tumor that occurs in the pituitary gland, commonly known as pituitary adenoma, is one of the common neuroendocrine tumors, accounting for about 10 to 15% of central nervous system tumors. The vast majority of pituitary adenomas are benign tumors. With the widespread use of MRI scanning in clinical practice, the sensitivity and specificity of the diagnosis of pituitary tumors increased significantly [1]. In our department, we retrospectively analyzed 42 cases of pituitary adenomas confirmed by surgery and pathology and MRI plain scan + enhancement to summarize the significance of MRI enhanced scan in the diagnosis of pituitary tumors. Pituitary adenomas originate from the benign enlargement of the anterior pituitary epithelium
