本文对４３例垂体微腺瘤作了分析研究，以便了解其临床特征及病理分类特点，结果显示垂体微腺瘤临床主要以继发性闭经、溢乳为特点。垂体ＣＴ轴面薄层增强扫描加矢状、冠状重建是经济、可靠的诊断方法。腺瘤病理分类亦以催乳素腺瘤为主（５３．４９％），其他是混合性腺瘤（１１．６％），生长激素腺瘤（６．９８％），促肾上腺皮质素腺瘤（４．６５％），促肾上腺皮质素细胞增生（２．３３％），未进一步分类（１８．６％）。免疫组化染色是必需的，强调网纤维嗜银染色在病理诊断上的重要性。术前诊断与病理诊断大致相符，手术效果良好
In this paper, 43 cases of pituitary microadenomas were analyzed and studied in order to understand its clinical features and pathological classification characteristics, the results showed that the clinical pituitary microadenomas mainly characterized by secondary amenorrhea and galactorrhea. The thin-section contrast-enhanced sagittal and coronal reconstruction of the pituitary CT axial plane is an economical and reliable method of diagnosis. The pathological classification of adenomas was also mainly prolactin adenomas (53.49%), other mixed adenomas (11.6%), growth hormone adenomas (6.98%), corticotropin adenomas (4 .65%), corticotrope cell proliferation (2.33%), no further classification (18.6%). Immunohistochemical staining is necessary, emphasizing the importance of silver fiber axonal staining in pathological diagnosis. Preoperative diagnosis is roughly consistent with pathological diagnosis and good surgical results
